* "In this gripping science fiction thriller, Fagan reiterates her strength as a masterful world builder. . . . Fans of Scott Reintgen and Fagan’s earlier works will eagerly embrace this thought-provoking, emotionally resonant novel."

– School Library Journal, starred review

"Delta's journey from parroting propaganda to thinking for herself is the kind of compelling and believable that has brought decades of readers to Lois Lowry's The Giver and newer generations to Donna Barba Higuera's Alebrijes."

– Shelf Awareness

“Readers will be drawn in by the warm, wholesome cast of characters. A hopeful, exciting, and action-packed adventure."

– Kirkus

“[E]lectric . . . . Concise, economical storytelling and steady pacing mold a vast dystopian world whose charismatic leads evoke protective warmth from the jump."

– Publishers Weekly

"It’s an exquisitely crafted sci-fi mystery, and though suspense and action abound, it makes time for humorous asides and moments of wonder. An extensive history and mythology flesh out the fascinating world, and Delta’s internal journey feels as profound as her external odyssey. An exhilarating examination of the power of stories, truth, and kindness."

– Booklist

"A unique setting with an intriguing history, a dystopian society of secrets and hierarchies, and a tween learning on the fly just how bold she can be—there’s a lot here to recommend to sci-fi fans."

– BCCB

"From the intriguing premise to the rapidly unspooling mystery of the bloodstorms and how they relate to the Founders, Fagan keeps things moving in this energetic sci-fi tale, where every ally Delta makes takes her one step closer to understanding what has been placed in her head. The stakes get higher throughout, so that by the end planetary survival is on the line and the deceit has been stripped from every bastion Delta’s life is founded on, leaving her the better for it."
