Dead Drop — Carolyn Jewel

The demon Palla is a warlord's enforcer, a stone-cold killer. Wallace Jackson is a pacifist witch with a dangerous power. He wants nothing to do with humans until he needs Wallace and her unusual ability to help him free Avitas, his former lover, from a living death. His plan is to work with Wallace until she has control of her magic, free Avitas's spirit from unimaginable suffering, and then, if he's still alive, walk away. Done. Wallace Jackson has been recruited to train with a group of street witches being taught to work with demons sworn to the local warlord. After weeks of failure, Wallace has decided there's no point in continuing. One of the other witches is making her life hell, and any attempt to work with the demons leave her sick for days. No one is more shocked than she is when Palla, one of the demon warlord's most deadly assassins, proves her wrong. To say they dislike each other is an understatement, and, yet, after nearly killing her, he wants a favor. The problem is, she can't say no. No part of Palla's plan involves falling for Wallace. He doesn't like her, she doesn't like him, and that suits them both just fine. But as they work together, they discover they have more in common than either of them imagined. Dead Drop is set in the My Immortals series world where demons and magic-using humans called the magekind are not quite getting along and most people have no idea they're living in what amounts to a magical war-zone.
