From New York Times bestselling author Mackenzi Lee comes a thrilling tale set in the world of the Masters of the Universe live-action film, where Eternian warrior Teela must decide how much she's willing to sacrifice to save the people--and home--she loves.

A FALLEN KINGDOM
Four years after Skeletor decimated the kingdom of Eternos, Teela and the scattered refugees of Eternia survive by never staying in one place for long. When a brutal storm of acidic rain deep within the Evergreen Forest leaves their camp ravaged and hope at its thinnest, some, like Teela's friend Locke, begin to plan for a future beyond Eternia. But Teela knows her father Duncan, the once-mighty Man-At-Arms, won't survive leaving the land he swore to protect.

A FORBIDDEN ALLIANCE
Desperate to save her people, Teela ventures to Darksmoke to bargain with the ancient dragon Granamyr. He bestows upon her a vial filled with a mysterious, powerful elixir--and no instructions on its use. Enter Evil-Lyn, Skeletor's ruthless second-in-command, who intercepts Teela with a dangerous proposal: an alliance. In exchange for the vial's secrets, Teela and the Heroic Warriors must someday help the sorceress overthrow Skeletor himself.

A MAGIC THAT COULD SAVE--OR DESTROY--THEM ALL
The vial heals the sick and brings food back to empty tables--until the forest around the camp begins to change. Rivers vanish. Trees peel to bone. Creatures flee. As the land around them withers at an ever-increasing pace, Teela must confront an impossible question: Has the very magic she used to save her people doomed Eternia instead?
