"Three young ghost trappers take on deadly wraiths and solve an old murder case in the bargain to kick off Stroud's new post-Bartimaeus series. The work is fraught with peril, not only because a ghost's merest touch is generally fatal, but also, as it turns out, none of the three is particularly good at careful planning and preparation. A heartily satisfying string of entertaining near-catastrophes, replete with narrow squeaks and spectral howls."--Kirkus Reviews

"Stroud shows his customary flair for blending deadpan humor with thrilling action, and the fiery interplay among the three agents of Lockwood & Co. invigorates the story (along with no shortage of creepy moments)." --Publishers Weekly

"A pleasure from tip to tail, this is the book you hand the advanced readers that claim they'd rather read Paradise Lost than Harry Potter. Smart as a whip, funny, witty, and honestly frightening at times, Stroud lets loose and gives readers exactly what they want. Ghosts, kids on their own without adult supervision, and loads of delicious cookies." --Elizabeth Bird, School Library Journal

"...Stroud writes for a younger audience in book one of the Lockwood & Co. series and delivers some chilling scenes along the way."--Booklist
