Scent of Valor by Annie Nicholas

Courage can bloom in the meekest of hearts.
After twenty years, Kele can finally change into wolf shifter form. By tooth and claw, she’s determined to climb the Payami pack hierarchy one challenge at a time until she’s the alpha. Except her parents arrange her marriage to a werewolf from a rival pack. Nobody cares that her heart’s already been stolen by the most unsuitable wolf possible—Peder. She’d gladly runaway with him but he stopped answering her letters and disappeared.
Peder spends every moment of his forced separation from Kele training to be a hunter. Learning to fight and be the type of wolf shifter she deserved. When he hears of Kele’s arranged marriage, he fears he’s waited too long. But he isn’t giving up. He’ll fight for her even if it means his life.
On his journey to confront her future mate, Peder is attacked and wakes in a cage, helpless as a band of vampires attack Kele’s mating party. Separated by social standing, thrown together by tragedy, they must work together to survive. And find out if their attraction is merely puppy love, or a bond that’s stronger than time.
