If you could learn the identity of your one true love—even though you will never meet—would you? Years have passed since refugees from a ruined earth took to space, eventually settling a new system of planets. Science has not only made the leaps necessary to allow time travel, but the process engineered a strange side effect—predicting your one true love. If you could save your one true love from an untimely death, would you be able to resist? Sixteen-year-old Kaia Vespasian is an apprentice to the Historians—a group charged with using time travel to document the triumphs and failures of the past—and she can’t resist a peek at her long-dead soul mate in Ancient Egypt. Before she knows it, she’s broken every rule in the book, and the consequences of getting caught could destroy more than just her new romance. Or would you have the strength to watch him die? But when Kaia notices a fellow classmate snooping around in a time where he doesn’t belong, she suspects he has a secret of his own—and the conspiracy she uncovers could threaten the entire universe. If her experience has taught her anything, to changing history means facing the consequences. The Historians trained her to observe and record the past, but Kaia never guessed she might have to protect it—in a race across time to save her only chance at a future.

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.
