Books in Fate Bound series

A werewolf's first instinct is to protect those weaker than himself. But Jack chose to protect the wrong girl. After a brutal encounter, Ava awakes to a new life of heightened senses and supernatural speed. But she isn't like other werewolves, and her special qualities put her--and her new family--in unimaginable danger. Her very existence threatens a precarious balance--one that can only be set right by her death.
