It's been three years since Lilah Quinn stumbled upon the bones of her biological mother, thereby solving the mystery of Willow's long-forgotten disappearance. Since then, Lilah has been working off-book as Sheriff Reid's star detective, solving decades-old cold cases with the help of those closest to the crimes - the victims themselves.

But when Lilah's newest case hits a dead end, she's forced to do something she's never done before: speak to the murderer himself. Unfortunately, his "ghost" isn't interested in helping her, nor is he willing to play by her rules. Because, unlike all the others, this ghost is able to exist apart from his bones, untethered even by time.

And now that he's been freed, he's got a bone to pick.
