"It's been twenty years since Detective Chelsey Calhoun's sister vanished. Ever since, Chelsey's been searching: for signs, for closure, for other missing girls. But happy endings are rare in Chelsey's line of work. Then, a glimmer of hope. Local teenager Ellie Black, who disappeared without a trace two years earlier, has been found alive in the woods of Washington State. Only--something isn't right with Ellie. She won't say where she's been or who she's protecting. Now, it's up to Chelsey to find answers before it's too late: for herself and for the memory of her sister. But mostly for the next girl who could be taken--and who, unlike Ellie, might never return"--Provided by publisher.
