Heaven and Hell
DISCLAIMER: Nothing in this book is supposed to be religiously accurate. I made everything up.
Mariel is an Archangel who is sent to Earth to kill a particularly annoying Demon. This Demon, Blacc, along with her human friend Nick, befriend Mariel instead.
When the Angels find out about their friendship, they trick Blacc into going back to Hell, where an Angel-made conflict threatens to keep her there. Will the power of the relationships the three of them formed be enough to stop everything that's gone wrong?
