After everything that happened last semester and so many of the people she loves depending on her, Kaia Vespasian knows the best thing to do is keep her mouth shut, her butt in her chair, and her head down. In a few months she’ll be a certified Historian, and with the position could come some leverage. When the Elders announce that inconsistencies have been found in the holofiles—people disappearing and possibly reappearing, as well—Kaia worries that her meddling has made a mess of things in the past…and the present. With her roommate Sarah still angry over the imagined betrayal of Kaia with her boyfriend, Oz, her options for cohorts are limited. She and Oz decide to team up to try to figure out what’s going on in the past, and whether the sneaky Elders and their Return Project have anything to do with it. Kaia’s focused on the lives of her parents, her brother, and her best friend, but what if the lives of everyone in Genesis are on the line? First, she’ll have to figure out how to set the timeline right. If she can do that, Kaia will face an even harder task—putting the greater good above the lives of the people she loves.
