Bound By the Moon by Christine Michelle

Jessica St. Marks De’ Lune has it all. She is the famed white wolf of legends. Her mate was destined to be King, and they’re having a baby. Happily ever after is only a heartbeat away for them!
Unfortunately, female wolves are disappearing. Hunters of old, who were made to kill the dark ones, are now hunting their kind. The dark ones have surfaced, and to top that off, a very unique and unheard of prison break make happily ever after seem like it’s never going to happen.
It’s going to take a miracle, maybe several, to bring Jess’s people together, keep them safe, and bind them to a common cause. If it works, they may all just find a little bit of happy. If it doesn’t, she’s damned them all to hell.
