Demon for Hire

Alcarzara did something almost impossible: she got kicked out of Hell. Her crime: being too soft on humans. So now she has to walk the Earth (Heaven won't take her in, and Hell won't take her back) and somehow find a way to fit in with those who she formally tormented. She finds a job that she might be good at doing, but almost immediately she runs into a case that even a former demon can't handle.
Her client is a teenager girl suffering from demonic possession! Will Alex Zara (as she now calls herself) take the case, or walk away? How much of the evil demon is still inside her? How much does she want to reform? And what can she do anyway when faced with a more powerful demon than she ever was?
