San Andreas Shifters, book 1: The Sumage Solution
G. L. Carriger2017

Max fails everything - magic, relationships, life. So he works for DURPS (the DMV for supernatural creatures) as a sumage, cleaning up other mages' messes. The job sucks and he's in no mood to cope with redneck biker werewolves. Unfortunately, there's something oddly appealing about the huge, muscled Beta visiting his office for processing.

Bryan AKA Biff (yeah, he knows) is gay but he's not out. There's a good chance Max might be reason enough to leave the closet, if he can only get the man to go on a date. Everyone knows werewolves hate mages, but Bryan is determined to prove everyone wrong, even the mage in question.
