I guess you're probably wondering about the next girl. Because there's always another girl, right? A girl waiting to be taken. To be swept away. I'll tell you about her.

It's been twenty years since Detective Chelsey Calhoun lost her sister, and she's been searching ever since: for signs, for closure, for other missing girls. Happy endings are rare in Chelsey's line of work.

Until, two years after her disappearance, local teenager Ellie Black is found alive in Washington State woods.

But something's not right about her: where has she been, and who is she protecting?

Chelsey has to find out. For herself, for her sister, and before the next girl is taken.
