School Library JournalGr 7 Up—This title covers the same time period as The Obsidian Blade (Candlewick, 2012), but from Lah Lia's point of view. She explains her origins as a Pure Girl, raised and groomed for eventual sacrifice to atone for the sins of society's past. At her sacrificial ceremony, an interruption occurs with the sudden appearance of Tucker, introduced in the first book, who has been time-traveling between historical events of the future and distant past through portals called diskos. Tucker's presence creates a one-in-a-million chance for Lah Lia to escape her pending doom by jumping through one of the diskos. When she lands in the new world, she sustains multiple life-threathening injuries, but is healed by an advance core of medical specialists termed Medicants.
