Sanctuary — Rye Brewer

A half-blood by birth.
Anissa Garnet is half-fae, half-vampire. And she's not the daughter of just any fae, she's the daughter of Gregor, the leader of the fae. Except now she's made the mistake of walking away from her fae kind.
As if that wasn't bad enough, she left her mother's kind -- vampires -- behind.
Now this half-breed has gone rogue, but she hasn't done it alone.

Vampire clan leader no more.
Jonah Bourke not only stepped down from being a clan leader, he also left behind his entire clan, the one he was destined to rule. All to merge his fate with Anissa, the slayer that had been sent to kill him.

New Alliances, old foes.
The Sanctum provides more than sanctuary. It provides answers, which sometimes leads to more questions, and then even more threats.
