Mackenzie "Mac" Harris fled her hometown of Bluff Point, Maine, after being left at the altar--and seeking solace in the arms of her best friend's off-limits brother. Now, seven years later, she's back to attend her best friend's wedding--safe, or so she thinks, from the mistakes of her youth. But Gavin Tolliver has never forgotten the woman who has always held his heart. And when Mac rescues a stray puppy named Tulip, only Gavin, the town's veterinarian, can help. With a little assistance from Tulip, Gavin vows to make Mac realize that their feelings are more than just puppy love.
