Sunshine at Midnight by Ashlynn Monroe

Werewolves were the stuff of books and movies for Tansy Sunshine Tanner until the day her mother brought home a new boyfriend.
As a rare werewolf bite survivor, Tansy is an oddity. Most everyone living in Lyacon, Wisconsin was a born werewolf. Add the discrimination she faces as she the only bi-racial resident, and all she wants to do is leave. But leaving would require money to cover her tracks and hide. Werewolves would kill to protect the secret of their existence.
At almost twenty-one, Tansy has squirreled away almost enough money working at the local watering hole, The Howl. One thing she has plenty of is almost.
Xander Wolfsbiss is lost.
Every werewolf awakens at twenty-one able to sense his or her mate. Xander found his. He loved her with that electric connection between fated souls. She died. Five years later, he drinks away his sorrow and spends too much time and money at The Howl. He isn’t doing much with his life until the day he steps in to protect the young bartender from the alpha and his son.
What he never sees coming is sunshine at midnight when someone finally shares his grief in a way no one else could. This time he’ll protect the woman he loves. He’ll fight to his last breath, if it means he never has to live in darkness again.
