Seth by Valerie Ullmer

Immortals have been a part of Seth’s world since he barged into Kai’s life at the age of twelve. And having a group of shifter and vampire assassins he considered family, he thought that he’d seen it all and that nothing would surprise him. But the one night he met Aubrey changed his world, and he’d never been so happy to be wrong.

Aubrey was used to seclusion, even before she had been turned into a vampire. She’d never dreamed of a life outside her tiny little world, but that was until she met Seth. Before she could understand her reactions, she ran from him. But she couldn’t stay away. The more she gets to know him, the stronger the connection between them solidifies.

When Seth tells Aubrey that he is her mate, will she take a chance and keep him forever?
