Christian is the Catholic Church's best executioner. Dedicated. Devout. Deadly. Ever since the Church saved him from the decimated ruins of his hometown, his commitment to their cause has been unshakable.

Then he's sent to execute Lilith, who lives in Seal Beach, California. He's baffled. Lilith is afraid of men. The Church believes she's a succubus, but he just can't see it. Yet the way men—both human and monster alike—act as if they've been possessed whenever she's near is disturbing.

With lustful men attacking Lilith and monsters attacking him for being near Lilith, Christian must uncover what's really going on, and soon, or innocent blood will run through the streets—as will his own.

Love. It can kill a man.
