Heather Simmons is excited to start a new job in Alberta, Canada, as a glaciologist. But when a minor accident leaves her trapped on a hiking trail overnight, she finds herself facing a burly mountain man and a pair of grizzly bears. From that moment forward, things could not get weirder. Isaiah Arthur knows instinctively that Heather is his mate the moment he scents her clothing before heading up the mountain to rescue her. The sensation is confusing since she is obviously human, and converting a human to his species is strictly forbidden. A rogue shifter takes Heather's transition out of Isaiah's hands, however. Isaiah is left with no choice but to take her home and find a way to inform her of her unintended fate, while fighting the intense need to make her his as soon as possible. The North American governing body, the Arcadian Council, is not amused by the rare turning of a human, and chaos ensues as Isaiah races against the clock to bind his mate to him forever before someone steps in the way and takes the opportunity out of his hands.
