The Blood Demon's Pet

Leviathan only wanted a new feeder. He ends up with something so much better.
Eryn is broken.
A werewolf who can't control his shift, Eryn is a liability to his pack. It wouldn't be so bad if his wolf would at least submit to the pack Alpha, but the beast inside him is feral. Eryn knows he won't be allowed to stay forever, but he has nowhere else to go. None of the other packs want him, either.
When his wolf goes too far one full moon, he's left with no choice but to flee. After putting his trust in someone he shouldn't, he ends up at a Flesh Market. Trapped in a contract he has no hopes of surviving, the last thing Eryn expects is to fall for his new master, a Blood Demon named Leviathan.
Leviathan is lonely.
One of the only Blood Demons allowed to remain on earth after the Collapse, Leviathan spends most of his free time with his nose in a history book. He can't remember the last time he went on a good rampage. He has a few trusted servants, and who needs more than that?
Unfortunately for him, he still needs to eat. His trip to the Flesh Market is supposed to be uneventful. Instead, it leads him to Eryn, a broken werewolf who manages to slip past all his defenses.
Can Leviathan move beyond old hurts to become the Master that Eryn needs, or will the young werewolf's fears come true?
