Keil Oakley Zepernick

A teenage girl living with schizophrenia begins to suspect her neighbor has kidnapped a child. Her parents try desperately to help her live a normal life, without exposing their own tragic secrets, and the only person who believes her is Caleb – a boy she isn’t even sure exists.

Caleb, a former government assassin in hiding, who resurfaces when his protégé, the equally deadly killer known as Banshee, discovers a bounty has been placed on Caleb's head.
