Marked Wolf by Lilliana Rose

Tamaska is hunted by vampires and needs protection.

Kodiak is the one to keep her safe. But after discovering he is a wolf shifter, Tamaska is confused and fearful. She vows to find the Blood Opal herself, unwittingly going straight into the vampire lair.
Kodiak must find another way to protect her before the vampires capture her for the completion of a ritual to heighten their powers. If he doesn’t, he will lose the woman he’s falling in love with, and the vampires will dominate humans making them their blood slaves.
Kodiak can’t stop this from happening alone. Will his pack be able to help him protect Tamaska? Or will the vampires hit them hard and begin a change that could bring chaos to the world forever.
