Hester asks Wilde—with whom she shares a tragic connection—to use his unique skills to help find Naomi.

Wilde can't ignore an outcast in trouble, but in order to find Naomi he must venture back into the community where he has never fit in, a place where the powerful are protected even when they harbor secrets that could destroy the lives of millions . . . secrets that Wilde must uncover before it's too late.
