Messner (Manhunt) has created a relatable, sympathetic character in anxious Ava, and her story is at its best when Ava's life remains centered around the norms of her school, friends, and multigenerational family.

The lesson here--not only about the values of not knowing, but about managing oneself in the face of uncertainty--will resonate and, hopefully, inspire.

Messner captures the anxieties of middle school girls. . . Would work well to spark discussions about problems that may plague middle school students.

Library Media Connection

Ava is a sympathetic and well-rounded character, and the relationship, conflicts included, between her and the more outgoing Sophie rings true. The writing is smooth and the dialogue believable. Firmly planted in realistic fiction with a single fantastical element, this story will appeal to Wendy Mass fans as well as those who love Messner's previous novels.

School Library Journal

Combines a fascinating concept with page-turning suspense. A wild roller-coaster ride.
