Cade is a werewolf and a demon hunter. Thanks to his supernatural nature, he is immune to demon bites and so he is a very good demon slayer, but he is alone. He chose long ago the hunter life to avenge the death of all his family and even when an alpha proposed him to be part of a pack, he refused. Now years later he has a chance to not be alone: David, a very young guy, barely eighteen, asks him to be his apprentice.

Cade takes David in and makes him "pack", and for Cade this means treating David like a cub, embracing him at night when the kid has nightmares and giving him a blow job or two when he is agitated after an hunting... well for sure David likes the treating and he would be happy to reciprocate, but Cade seems to believe that if he allows to the kid to go even further in their sexual exploration, he will be scared by the idea to be "gay". All right this is maybe one of the thing I don't exactly understand: how can Cade believe that David is not gay? The kid likes to much what they do together and he also tried in the past to reciprocate when Cade was sleeping, and only cause Cade interrupted him, the kid didn't finish. And then he is too eager to do more to not being desperately in love and totally gay.

In the end the decision is taken to Cade, since David is badly wounded and only becoming a werewolf he could survive. If he manages to remain alive through the changing...

The story is not very long, less than 80 pages and it has a strange structure: the main story is a night on Cade and David's life, the night when David is wounded; throught the night both Cade and David remember how they met and what they shared in the past, to at the end of the night, arriving to the finally decision: turning or not turning David? And since it seems that bodily fluid exchange (of every nature) allows a better changing, the procedure can be pretty erotic... bordering in almost hard!
