Rebecca Dunn has been studying Lycan society her whole life, so when werewolf billionaire Cain Fitzpatrick offers her a tour of his pack's estate, she knows she can't refuse. Not only will she be the first anthropologist to step into a werewolf designated zone, but he's going to be by her side explaining everything the whole time. As luck would have it, the first day she visits lands on the yearly celebration of the werewolf's fertily rites, and Cain has asked her to take the position of honor as his mate. Will Rebecca be able to accept his offer to be his in front of his whole pack hard and without protection?
