School Library JournalGr 6–9—The eye-catching cover is the best part of this novel, an uneven mixture of science fiction, fantasy, and postapocalyptic elements, set sometime around 2153. When 16-year-old Glennora was 6, her mother disappeared across the Rift, the restricted borderland that is reputedly full of monsters and magical creatures. Her scientist father claims to have built a bracelet-shaped device that can change reality on the other side of the Rift and allow them to bring his wife back. The teen thinks that her father is delusional but is proved wrong after the Authority arrests him and she and her friend Kevin are forced to flee across the Rift to avoid being shot. On the other side in Magisterium they discover that their technology doesn't work but Affinity (magic) does.
