While channeling Robin Hood's "steal from the rich and give to the poor" attitude at a local politician's house, ex-con Katie Logan witnesses a forced suicide. Dirty or not, supernatural or not, he didn't deserve to die, especially not by his own hand. But with her record, stepping forward as a witness isn't an option. On the run from the police and the murderer, she turns to The Bound Ones for help.
When a beautiful woman comes to The Bound Ones, half-angel assassin Cain is immediately drawn to her. But when she fingers him as the killer, he can come to only one conclusion. The twin he thought was dead is very much alive…and trying to send him a message. Unfortunately, that message is: "You're next."
It's a race against time as Cain fights to save the woman he's falling in love with before his brother Abel destroys them both.
