Devil Bound: The Devil's Necromancer Part One. Hellbound Gods, #1

Lionel Hawkes is a necromancer and police consultant, and he has a problem; Lucifer, also known as the Devil. Lionel can't seem to get rid of him although he's tried. Repeatedly. Lucifer always gets what he wants. He has the looks, he has the magic, and no one can resist his charm. Except that one necromancer who is altogether too cute to be left to his own devices. In addition, his crime-solving job gets him into contact with all kinds of unsavory substances and people, and Lucifer does not approve.
While a murder case cuts close to home, Lionel has to navigate getting rid of the Devil and solving the case, and being a professional necromancer, he feels pretty confident that nothing can go wrong. He's wrong about that. Devil Bound contains banter, hellpoodle drool, a necromancer who attracts zombie goo and other questionable substances, several divine creatures, and a clean floor fetish, none of which make life any easier for our necromancer.
