Coven by Mell Eight

Kana is a rare male witch ostracized by his coven. When he claims two familiars, rather than the standard one, he knows he has to run away to keep his coven from taking advantage of his power. After years of constantly looking over his shoulder, Kana realizes he should have been paying better attention to what’s right in front of him. He’s drawn the interest of a different sort of coven: vampires.
Vampires, and the werewolves who protect them, want power, and Kana has a lot of that. Even with the support of his familiars, Kana isn’t sure if he’ll survive the attentions of the vampires. Except, perhaps it’s the werewolves, and one handsome wolf in particular, that Kana ought to be afraid of.
