When a human foot washes ashore at Ebey's Landing on Whidbey Island, it's the latest puzzling turn in an old mystery. Feet have been showing up on beaches all over Puget Sound and British Columbia for years. Whose feet are they, and how did they get here? Is a serial killer at work? Or did the victims die in a plane crash or capsized boat? For Sheriff's Deputy Katarina Brown, the search for answers takes her deep into the lives and stories of five missing women and the circumstances that put them in harm's way. What she learns forever changes the lives of those left behind.
