Unstoppable Bear by Kendal Davis

Amber couldn’t go back to her old life…
…but she didn’t know the Montana wilderness would turn out to be everything she needed.
When Amber stepped into the Cave & Claw Emporium to beg for a job in the off-season, she found herself stitching up a jagged wound on the muscled torso of the sexiest man she’d ever seen. There was no way that was a wolf bite, right? Her big-city nursing degree hadn’t prepared her for anything like that. It also hadn’t been enough to shield her from the abusive surgeon fiancé she’d left behind.
Mike McCabe was a grizzly bear shifter who ran the prosperous family business that kept him and his brother free to roam the forest as trekking guides. He loved the small-town world of South Pines, where shifters took care of each other. His life was just perfect, except for the jostling politics, long-standing family feuds, and his gnawing sense of doom that he would end up settling for a loveless marriage.
When Mike met Amber, his world turned upside down. His inner bear roared wildly at him that Amber was his mate. Mike couldn’t stop thinking about enfolding Amber in his strong arms and ensuring her safety while crushing her lips with his. This bear shifter was going to do whatever he needed to do to keep Amber close to him.
She was his mate.
Forever.
Even if Amber’s old life came back to threaten their happiness just when things were heating up in the best possible way.
No damn way was anybody going to stop Mike McCabe from protecting her.
