Creature by Kim Fielding

Alone in a cell and lacking memories of his past, John has no idea who—or what—he is.

Alone on the streets of 1950s Los Angeles, Harry has far too many memories of his painful past and feels simply resignation in facing his empty future.

When Harry is given a chance to achieve his only dream—to become an agent with the Bureau of Trans-Species Affairs—all he has to do is prove his worth. Yet nothing has ever come easy for him. Now he must offer himself and John as bait, enticing a man who wants to conquer death. But first he and John must learn what distinguishes a monster from a man—and what a monster truly wants.
