Wilde

Thirty years ago, a child was found in the New Jersey backwoods. He had been living a feral existence, with no memory of how he got there or even who he is. Everyone just calls him Wilde. Now a former soldier and security expert, he lives off the grid, shunned by the community - until they need him. A child has gone missing. With her family suspecting she’s just playing a disappearing game, nobody seems concerned except for criminal attorney Hester Crimstein. She contacts Wilde, asking him to use his unique skills to find the girl.

Discovered living a feral existence in the Ramapo mountains of New Jersey, he has grown up knowing nothing of his parents, and even less about his own identity. When a match on a DNA database puts him on the trail of a close relative, Wilde thinks he might be about to solve the mystery of who he really is. Only this relation disappears as quickly as he's resurfaced. Wilde continues his research, becoming caught up in a community committed to exposing anonymous online trolls. Then people start to die and it soon becomes clear that a serial killer is targeting this secret community.
