The Blood Wolf by Alessa Thorn

Abominations don’t get fated mates. And yet here she is, dying at his feet.

Feared by both wolves and vampires, the last thing Thor expected was to have a wolf fall at his feet and ask for help. He shouldn’t get involved in pack politics, and wargs shouldn’t have mates, but one hit of her scent, and every part of him knows that this she-wolf belongs to him.
Nicola was raised an Alpha’s daughter, but nothing since her father’s death has gone right. The new pack leader has kept her imprisoned, trying to force a mating bond with her so she won’t share the secret she uncovered: the wolves want to start a war with the vampires, and she will do everything she can to stop it.
When her inner wolf leads her to Lord Thor, Viking vampire and scariest bastard alive, she knows that with his help, she can take down her old pack before they tear Inferno apart. It’s taboo for wolves and vampires to mix, so the fact that Thor is her fated mate and makes every part of her burn is just something else the pack will want to kill her for.
The wolves are about to get a lesson in what happens if you mess with Thor and his wargs. You play Viking games, expect to win Viking prizes, and Thor isn’t going to stop until Nicola is safe and his forever.
