Orphaned in a violent rogue attack, and the only surviving member of her pack, Catalina survives alone in the wilderness until one night when Aiden appears, a great black wolf whose very essence turns Catalina's world upside down.  When passions collide, Catalina sets out on a mission of vengeance, while Aiden, an alpha who has long been searching for his mate, fights to save her, from the rogues and from herself.
