Seven years ago, young Stella Pierce vanished from the face of the earth. Now her grieving, broken family-along with Detective Orson Cheever, who never stopped working her case-is stunned by her mysterious return. The now-teenage girl claims to have spent her missing years in the company of Travelers-extraterrestrial nomads-voyaging through space. Despite her family’s effort to keep Stella’s incredible tale secret, the story becomes a national sensation. Most people want to discount her story, saying it’s the result of trauma; only Detective Cheever seems to want the same thing Stella does: the truth. The enigmatic Stella finds herself in the eye of the storm while vying forces-some visible and some not-swirl around her. Is it her tale that is incredible, or is it Stella? As new questions surrounding the girl gain terrifying urgency, Cheever learns that there is nothing-and no one-he can trust.
