Named a Best Book of 2021 by the Financial Times and a Best Science Book of 2021 by The Guardian

"Rovelli is a genius and an amazing communicator... This is the place where science comes to life." ―Neil Gaiman

"One of the warmest, most elegant and most lucid interpreters to the laity of the dazzling enigmas of his discipline...[a] momentous book" ―John Banville, The Wall Street Journal

A startling new look at quantum theory, from the New York Times bestselling author of Seven Brief Lessons on Physics, The Order of Time, and Anaximander.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving.

Helgoland is a treeless island in the North Sea where the twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious.

As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness.

Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it.

A dynamic re-envisioning of the tarot, including tarot card imagery, that describes how the tarot is queer, that the archetypes are alive, and that tarot doesn't tell the future; it creates it.

Radical Tarot meets the tarot in a space of evolution, deconstruction, and creation, using the historical and common meanings of the cards as a launchpad for digging into limiting beliefs and societal conditioning and unlocking the personal truths beneath.

The Fool's Journey is re-envisioned as a journey to non-binary thinking, the gender essentialism is ousted from the Major Arcana and the Court Cards--and all the cards--are reframed through a non-hierarchical, anti-capitalist, and intersectional lens. The archetypes are re-imagined in modern, progressive, and queered contexts. For example:

• The Empress and the body positivity movement
• Justice, not in the legal sense, but as ethical discernment and accountability
• Temperance and transcending the gender binary
• The Devil and anti-capitalism
• Judgement and revolution

Radical Tarot also touches on Charlie's personal story of how tarot helped them embrace their queerness, leave their marriage, and radically change their life. It speaks to their queer awakening and how tarot became, for them, a tool for social justice and conscious awareness of the world around them. Their words and experience will help anyone who wishes to be closer to their own authentic selves.

Blending fantasy and science fiction, N. E. Davenport's fast-paced, action-packed debut kicks off a duology of loyalty and rebellion, in which a young Black woman must survive deadly trials in a racist and misogynistic society to become an elite warrior.

It's all about blood.

The blood spilled between the Republic of Mareen and the armies of the Blood Emperor long ago. The blood gifts of Mareen's deadliest enemies. The blood that runs through the elite War Houses of Mareen, the rulers of the Tribunal dedicated to keeping the republic alive.

The blood of the former Legatus, Verne Amari, murdered.

For his granddaughter, Ikenna, the only thing steady in her life was the man who had saved Mareen. The man who had trained her in secret, not just in martial skills, but in harnessing the blood gift that coursed through her.

Who trained her to keep that a secret.

But now there are too many secrets, and with her grandfather assassinated, Ikenna knows two things: that only someone on the Tribunal could have ordered his death, and that only a Praetorian Guard could have carried out that order.

Bent on revenge as much as discovering the truth, Ikenna pledges herself to the Praetorian Trials--a brutal initiation that only a quarter of the aspirants survive. She subjects herself to the racism directed against her half-Khanaian heritage and the misogyny of a society that cherishes progeny over prodigy, all while hiding a power that--if found out--would subject her to execution...or worse. Ikenna is willing to risk it all because she needs to find out who murdered her grandfather...and then she needs to kill them.

Mareen has been at peace for a long time...

Ikenna joining the Praetorians is about to change all that.

Magic and technology converge in the first part of this stunning debut duology, where loyalty to oneself--and one's blood--is more important than anything.

One of the finest and best-selling horror novels of the 1970s returns at last to chill a new generation of readers

In the isolated farming community of Harlowe, New Hampshire, where life has changed little over the past several decades, John Moore and his wife Mim work the land that has been in his family for generations. But from the moment the charismatic Perly Dunsmore arrives in town and starts soliciting donations for his auctions, things begin slowly and insidiously to change in Harlowe. As the auctioneer carries out his terrible, inscrutable plan, the Moores and their neighbors will find themselves gradually but inexorably stripped of their possessions, their freedom, and perhaps even their lives ...

A chilling masterpiece of terror whose sense of creeping menace and dread increases page by page, Joan Samson's The Auctioneer (1975) is a rediscovered classic of 20th-century fiction. With echoes of Shirley Jackson's "The Lottery" and Stephen King's Needful Things, Samson's novel returns to print at last in this long-awaited new edition, which features an introduction by Grady Hendrix (Horrorstör, Paperbacks from Hell).

"Buy this book ... there is no way to stop reading it, once you've started!" - Baltimore Sun

"A well-made piece of dynamite ... For all their talk, the author seems to be saying, men will permit their souls to be carried away bit by bit and auctioned off to the highest bidder. Samson has written a suspenseful, engrossing novel with the most gripping and violent ending we've encountered for some time."--Newsday

"A frightening novel . . . a powerful book from a powerful writer."--The Grand Rapids Press

"A novel you may never forget . . . a tight classic."--San Diego Tribune

"Brilliant, compelling . . . Add a powerful twist at the end and you have a total novel that takes hold of the reader on Page One and never lets go until the finish. This just could prove to be one of the top thrillers of the year."--Dayton News

From prize-winning and international bestselling author Elodie Harper, the second book in the Wolf Den Trilogy follows Amara as she escapes her life as a slave in the city's most notorious brothel, the Wolf Den. Her survival depends on the affections of a man she might not know as well as she once thought . . .

The life of a courtesan in Pompeii is glamorous yet perilous. At night in the home her patron bought for her, the house with the golden door, Amara's dreams are haunted by her past. She longs for her sisterhood of friends--the women at the brothel she was forced to leave behind--and worse, finds herself pursued by the cruel and vindictive man who once owned her. To be truly free, she will need to be as ruthless as he is. Amara knows her existence in Pompeii is subject to Venus, the goddess of love. Yet finding love may prove to be the most dangerous act of all.

Readers of Circe, The Song of Achilles, and other novels based on Greek mythology, as well as fans of inspiring feminist historical fiction exploring the worlds of Ancient Greece and Rome, will love Harper's acclaimed Wolf Den Trilogy. The first book in the trilogy, The Wolf Den, was a Waterstones Fiction Book of the Month and a critically acclaimed UK bestseller.

Founder and CEO of consulting firm Change Cadet Dr. Akilah Cadet shares a powerful, incisive look at where we are in the fight to dismantle white supremacy--and what we urgently need to do next​.

This is the story of how I became an unapologetic Black disabled woman in a white world. This book is for people who look and live structurally like me to be valued, seen, heard and perhaps some advice on how to navigate life amongst white supremacy. This book is also for white people who have been "doing the work" since the murder of George Floyd to read my story and be able to clearly see systemic oppression, racism, and ableism. There are books sharing the historical context of white supremacy, providing tips on how to be an ally or anti-racist, and firsthand experiences from Black Indigenous People of Color (BIPOC) which are important. I push the conversation that leads to real change through my story. This book is for the Black woman who is looking to been seen and soft in shared lived experience. It is for the white person who is immersing themselves in the community they want to advocate for. It is for anyone who understands that learning and unlearning is lifelong.

White Supremacy Is All Around arrives as the U.S.'s ongoing racial reckoning has left readers searching for voices they can trust. BIPOC, disabled people, and other intentionally ignored Americans want to feel heard and empowered; organization leaders and allies invested in dismantling white supremacy want a framework for how best to contribute. Dr. Akilah Cadet speaks to all these needs, drawing from her life experiences and work helping leading brands build inclusive and equitable cultures to offer an informed perspective that prioritizes belonging. In a series of personal stories told with her trademark candor and wit, Dr. Cadet explores the long-term work required to combat structural oppression from her unique vantage point as a Black disabled woman. She tackles everything: from the 2020 "summer of allyship" and depression caused by workplace discrimination to navigating disability and building a consulting business, all with a little inspo from Beyoncé.

A powerful call for true accompliceship for non-Black people, and a way for Black people to see and celebrate themselves, White Supremacy Is All Around ushers in a new voice that is timely, urgent, and essential--and a vision we all need now.

There were Bridgertons before the eight alphabetically named siblings. In the fourth of the Bridgerton prequel series, following The Other Miss Bridgerton, we go back to where it all began. . . from #1 New York Times bestselling author Julia Quinn

She was given two choices...

Georgiana Bridgerton isn't against the idea of marriage. She'd just thought she'd have some say in the matter. But with her reputation hanging by a thread after she's abducted for her dowry, Georgie is given two options: live out her life as a spinster or marry the rogue who has ruined her life.

Enter Option #3

As the fourth son of an earl, Nicholas Rokesby is prepared to chart his own course. He has a life in Edinburgh, where he's close to completing his medical studies, and he has no time--or interest--to find a wife. But when he discovers that Georgie Bridgerton--his literal girl-next-door--is facing ruin, he knows what he must do.

A Marriage of Convenience

It might not have been the most romantic of proposals, but Nicholas never thought she'd say no. Georgie doesn't want to be anyone's sacrifice, and besides, they could never think of each other as anything more than childhood friends... or could they?

But as they embark upon their unorthodox courtship they discover a new twist to the age-old rhyme. First comes scandal, then comes marriage. But after that comes love...

Ed Piskor's Hip Hop Family Tree has been a global phenomenon and perennial bestseller since the first (of four) volumes was published in 2013, spawning multiple printings, fourteen comic books, and the author's wildly popular YouTube comics channel, Cartoonist Kayfabe (with fellow cartoonist Jim Rugg). Yet the series has never been collected under one cover. Until now.

This omnibus collection includes the original 360-page series with over 140 pages of extra material: a cover gallery of every HHFT book and comic book cover and back cover Piskor ever created, pages from the HHFT comic book series that have never been collected, new annotations of the entire series by Piskor, and much more. Plus, it features a foreword by Charlie Ahearn and an afterword by Bill Adler.

Hip Hop Family Tree is the entertaining, encyclopedic history of the formative years of the music genre that changed global culture. Piskor's cartooning crackles like Kirby and takes you from the parks and rec rooms of the South Bronx to the night clubs, recording studios, and radio stations where the scene started to boom, capturing the flavor of late 1970s New York City in panels bursting with obsessively authentic detail. With a vigorous and engaging Ken Burns-meets-Stan Lee approach, the battles and rivalries, the technical innovations, the triumphs and failures are all thoroughly researched and lovingly depicted. Like the acclaimed hip hop documentaries Style Wars and Scratch, Hip Hop Family Tree is an essential cultural chronicle and a must for hip hop fans, pop-culture addicts, and anyone who wants to know how it went down back in the day.

Rage Becomes Her is an "utterly eye opening" (Bustle) book that gives voice to the causes, expressions, and possibilities of female rage.

As women, we've been urged for so long to bottle up our anger, letting it corrode our bodies and minds in ways we don't even realize. Yet there are so, so many legitimate reasons for us to feel angry, ranging from blatant, horrifying acts of misogyny to the subtle drip, drip drip of daily sexism that reinforces the absurdly damaging gender norms of our society.

In Rage Becomes Her, Soraya Chemaly argues that our anger is not only justified, it is also an active part of the solution. We are so often encouraged to resist our rage or punished for justifiably expressing it, yet how many remarkable achievements would never have gotten off the ground without the kernel of anger that fueled them? Approached with conscious intention, anger is a vital instrument, a radar for injustice and a catalyst for change. On the flip side, the societal and cultural belittlement of our anger is a cunning way of limiting and controlling our power--one we can no longer abide.

"A work of great spirit and verve" (Time), Rage Becomes Her is a validating, energizing read that will change the way you interact with the world around you.

From the National Book Award-winning author Denis Johnson (Tree of Smoke) comes Train Dreams, an epic in miniature, and one of Johnson's most evocative works of fiction.

Suffused with the history and landscapes of the American West--its otherworldly flora and fauna, its rugged loggers and bridge builders--this extraordinary novella poignantly captures the disappearance of a distinctly American way of life.

It tells the story of Robert Grainer, a day laborer in the American West at the start of the twentieth century--an ordinary man in extraordinary times. Buffeted by the loss of his family, Grainer struggles to make sense of this strange new world. As his story unfolds, we witness both his shocking personal defeats and the radical changes that transform America in his lifetime.

What can we hope for at the end of the world? What can we trust in when community has broken our hearts? What would it mean to pursue justice without violence? How can we love in the absence of faith?

In a heartbreaking yet hopeful collection of personal essays and prose poems, blending the confessional, political, and literary, Kai Cheng Thom dives deep into the questions that haunt social movements today. With the author's characteristic eloquence and honesty, I Hope We Choose Love proposes heartfelt solutions on the topics of violence, complicity, family, vengeance, and forgiveness. Taking its cues from contemporary thought leaders in the transformative justice movement such as adrienne maree brown and Leah Lakshmi Piepzna-Samarasinha, this provocative book is a call for nuance in a time of political polarization, for healing in a time of justice, and for love in an apocalypse.

An inspiring and entertaining collection of unforgettable true stories about finding unexpected beauty in life's transitions--from Lin-Manuel Miranda, Elizabeth Gilbert, Quiara Alegría Hudes, and many more.

"The Moth taught me how to be vulnerable, how to take my time, and how to listen to someone else's story and share in their moments of triumph, laughter, or, yes, sometimes embarrassment with an open heart."--Mike Birbiglia, from the Foreword

An international rescue mission for Paddington Bear. A family matriarch running numbers in Detroit. An epic Lucha Libre showdown in Mexico City. A beach vacation spent looking for the Kennedys. Storytellers from around the world share times they found real beauty in the moments when their lives changed forever--for better or for worse.

Carefully selected by the creative minds at The Moth and adapted to the page to preserve the raw energy of stories told live, on stage, and without notes, A Point of Beauty features voices familiar and new. This collection offers a shared message: If we look closely enough, we can find power in strengthening frayed bonds but also in having the courage to walk away from things that no longer feed our spirit. Through these storytellers' passion and their hope, they teach us all about what's worth holding on to: our relationships with those we love the most, our understanding of ourselves, and--of course--gathering together to tell and listen to our stories.

Winner of the Hugo Award for Best Novel - Kim Stanley Robinson's classic trilogy depicting the colonization of Mars continues in a thrilling and timeless novel that pits the settlers against their greatest foes: themselves.

"One of the major sagas of the [latest] generation in science fiction."--Chicago Sun-Times

Nearly a generation has passed since the first pioneers landed on Mars, and its transformation to an Earthlike planet is under way. But not everyone wants to see the process through. The methods are opposed by those determined to preserve their home planet's hostile, barren beauty. Led by the first generation of children born on Mars, these rebels are soon joined by a handful of the original settlers. Against this cosmic backdrop, passions, partnerships, and rivalries explode in a story as spectacular as the planet itself.
