All Night Long by Megs Pritchard

Gray Strachan tolerates humans. Key might be the only exception, but since he is mated to Kelvin, a fellow vamp, he kind of has to. Humans were only good for two things: feeding and sex until he accidentally mates one.
Henry Boulder spent a few minutes with a hot man and now he’s ill. When hot man turns up and reveals he’s a vampire, Henry doesn’t believe him. In fact, Henry is now concerned that hot man is in fact nuts.
Can they both overcome their issues and make their mating work?
