“A fun and creative voyage with unexpected twists and energetic turns. . . . Rutkoski's creative imagery and beautifully descriptive thoughts create a world that you could happily get lost inside.” —Deseret News

“* Rutkoski builds on what worked in the first novel and heightens the stakes. . . . Strong characters and fast-paced plotting let this compelling installment stand independently, but the ending will leave readers eager for the next.” —Publishers Weekly, starred review

“This book is a wonderful mix of fantasy, action, science fiction, and even a bit of romance. It is a real pleasure to find a book so smooth in its transitions. Though it is incredibly imaginative, the storyline is easy to follow.” —San Francisco Book Review

“The fantastical journey of Tomik and Neel, and Petra's struggles with her captor, her education, and her love interest will engage fans of the first book and bring new readers to the series. An author's note (cunningly penned by Astrophil, Petra's clockwork spider) explains which characters and events are rooted in historical fact.” —School Library Journal

“[Readers will] be engrossed in a tale that is part mystery and part fantasy, with a reveal at the end so grotesque they'll be clamoring for the next book's release date. A true original.” —Kirkus Reviews
