The Alpha's Bite — Michelle Fox

For werewolf Adele Fleurgriffe chasing a constant high and being trapped in a vampire blood slave ring was a lot easier than being normal. But she's trying hard to change her life, to stop using drugs, to be a good guest of the Huntsville Pack and not think too much about the vampire who got under her skin in a way drugs never did.

Vampire Davian Sanglante tried to walk away from Adele once. He's no good for her, but she keeps showing up and telling him he's wrong. If she knew his deepest, darkest secret, she would run screaming. The problem is every time he sees Adele, it gets harder and harder to push her away...no matter how much danger that puts her in.

Full length shapeshifter, vampire paranormal romance novel. Standalone. No cliffhanger. 

Note: While you don't have to, you'll have more fun if you read The Alpha's Fight before this because that's where we first meet Adele and Davian.
