In the days before the Flood, Azaziel had been a Watcher, sent down to help God's creatures on Earth. He fell in love with one of Cain's granddaughters and they passed her mortal life in bliss.
Now he's imprisoned in the Los Angeles basin. His angelic brethren, Heaven's misfits, don't understand the longing Aza feels: once he had been loved entirely for himself.
The succubus Lorelei doesn't know any of this when she sets her sights on Azaziel. All she knows is that the angel's fall will bring glory to Hell and acclaim to any succubus who accomplishes it.
Of course, it never occurs to Lorelei that Azaziel might try to tame her by possessing her with a mortal girl's soul.
Can the succubus find an exorcist before the fury of Hell is unleashed?
