Bride of Lucifer: Hell on Earth #1

"I’m the angel in her. She’s the devil in me."

A little angel flew to Hell on Earth. And fell for the Devil...

After opening Hell on Earth, a Vegas-on-steroids tourist empire, Lucifer hosts the Bride Trials.

Astraea, a sweet but psycho angel finds herself bound to the Devil after her failure to kill him. She never imagined she'd end up Lucifer's spy, solving murders in the midst of a multi-race war. With the aid of a sentient snake, Astraea follows the murder trail to a female Dracula, a wingless angel Diviner, the high Demon of Lust, and ultimately into the heart of the Bride Trials.

To free herself from Lucifer and end the war, Astraea must conquer the Bride Trials, survive the wedding, and kill the Devil on the honeymoon. If she doesn't fall for him first...
