Dancing Moonbeam by Lynn Hagen

Over a lifetime Raidh has dealt with his critical father who completely disdains him, which has left him with enough baggage to fill a vault. When Raidh finally escapes the Unseelie realm, his father threatens to eliminate him. And just when he thinks things can’t get any worse, he meets his mate, who happens to be a wolf shifter. The problem? Mating outside of the Unseelie race is punishable by death.
When Jaytee finds his mate, things take off in the wrong direction. Raidh has a ton of problems, one of which is his underlying scent that causes him to crave the fairy’s blood. Not exactly a common trait among wolf shifters. That’s a vampire thing. Now he has to not only battle against the craving, but help his mate fight the obstacles that continually try to kill him, because not even death will separate Jaytee from his mate.
