Mating Instinct by Theresa Hissong

Ada Carlisle never knew anything outside the gates of her clan, but she isn’t oblivious to why the men were there to touch her. When she is put up for sale to the highest bidder, she flees her home clan for a chance at survival. After traveling for weeks, her bear calls to build a den for the winter months. Once spring arrives, she wakes scared and alone on the land of three male grizzlies.
The spring mating season comes with the discovery of a female bear shifter on the Morgan’s land. Rex Morgan knows immediately Ada Carlisle is to be his mate, but she’s too weak to complete the mating. When it is revealed her clan intended to sell her to a male in Montana, the Morgan brothers vow to take down the leader of the O’Kelly clan and bring justice to the male who paid for her hand.
