When alpha wolf Lakota Longtree sees a grizzly stalking a young woman in the Alaskan wilderness, he intervenes just in time. But the beast is no ordinary bear. He is a shifter of a different clan, an ancient enemy of Lakota's people, and Bear will not be satisfied until he has tracked down and killed the woman he perceives as a threat. Lakota's only choice is to make her a member of his pack, but that will mean teaching the headstrong girl that an alpha expects to be obeyed.
Biologist Carly Fowler has never put much stock in myths and legends, but after the ruggedly handsome man who so recently saved her life transforms into a wolf before her eyes, she is forced to accept that what he says is true. There is a terrifying creature hunting her and Lakota and his pack can keep her safe, but that will mean submitting to a stern, dominant alpha who will not hesitate to soundly punish her any time he feels it necessary.
Lakota gives Carly no time to ponder her situation, nor does he give her a choice in the matter. She will live with him until he is sure she is no longer in danger, and during that time she will do as she is told or face the consequences. It isn't long before Carly's defiant attitude earns her a painful, embarrassing spanking over Lakota's knee, but despite her fury at being punished in such a fashion she cannot help yearning for him to take her hard and thoroughly.
Over the coming days, Lakota takes on the role of Carly's firm but loving daddy, providing the structure and discipline she requires to adjust to her new life. Soon enough, however, his need for her becomes overwhelming, and he claims her as his mate, mastering her more completely than she would have ever thought possible. But will her presence end up tearing his pack apart?
