As per the author’s website on book #1:
When Roxie and her friend, Candice, decided on a girls’ night out she didn’t realize the Wulf’s Den would be more than she had anticipated. But Roxie soon learned to expect anything. The presence of a super-abundance of super good looking men surprised her and when the best of the bunch stared at her as if he wanted to devour her, surprise turned to amazement.
Beouwlf recognized her as his mate the instant she crossed his path and her scent filled his lungs. But he had to overcome one hurdle. She was not one of his kind–a werewolf. He had waited for years to find his mate and he would claim her even if she was a mortal. He would soon teach her all about werewolves.
