The Sleepless City3 books in series
Shades of Sepia Publisher's Summary
A serial killer stalks the streets of Flint, Ohio. The victims are always found in pairs, one human and one vampire.
Simon Hawthorne has been a vampire for nearly a hundred years, and he has never seen anything like it. Neither have the other supernaturals he works with to keep the streets safe for both their kind and the humans.
One meeting with Simon finds Ben Leyton falling for a man he knows is keeping secrets, but he can't ignore the growing attraction between them. A recent arrival in Flint, Ben finds it very different from his native New Zealand, but something about Simon makes Ben feel as though he's found a new home.
After a close friend falls victim to the killer, Simon is torn between revealing his true nature to Ben, and walking away to avoid the reaction he fears. But with the body count rising and the murders becoming more frequent, either, or both of them, could be the killer's next target.
