Immortal, Insatiable, Indomitable — Olivia Gates

Vidar, an immortal in the service of the Norse god Loki, is ready to die--until he lays eyes on the most beautiful mortal he's encountered in centuries. Not only is Kara sexy and eager to be ravished by him, but she also defends him from minions of his enemy...making her the only human to ever put their life on the line for him.

Vidar and Kara soon enjoy the unbridled ecstasy they seemed destined to share. Yet they know they can't be together for long. Vidar can sense that Kara will die soon--unless he can find a way to make her immortal, too....
