Their families call them the Gifted. They call themselves the Losts. And to everyone outside Brennex, they were ordinary people—until now. Libbi Wilder is the good kid. While her older siblings have traveled the galaxy having adventures, she's stayed home to run the family store. Someone has to, after all. Then a stranger shows up at the store, and people Libbi's age—the Losts—start going missing. Libbi and her best friend Mixin set out to investigate, but before they find answers, Libbi's brother and sister swoop in to save the day without being asked, reigniting old resentments. Libbi knows she'll always be the baby of the family, but if she can solve the disappearances, maybe she can finally win her siblings' respect. Except the truth behind the missing people is worse than she feared. With the long-held secret of their gifts now exposed, Libbi will have to rally the Losts—and harder still, work with her siblings and their partners—to save them all from falling under Ravel Corporation's control in this gripping conclusion to the Gifted of Brennex trilogy.
