Suddenly jobless, Darcy Conti becomes a tour guide for Sturgeon Widows Tours, a quirky family-run business on the shores of Lake Superior. As she settles into her new role narrating local history excursions, she fights an undeniable attraction to the one man she definitely can't fall for—the owner's son.

Fresh from a relationship gone sour, Sean Stetman plans to avoid dating—and his job at his parents' tour company—for the foreseeable future. He wants nothing more than time to fish, hike, and work on his cabin. But when the tour driver quits, he is suddenly back on board, reluctantly shuttling Darcy and the tour guests along the North Shore.

Together, Darcy and Sean survive unruly tourists, meddling mothers, and even an unscrupulous developer looking to give the Stetmans' tour company some fierce competition. Will their time on the tour bus drive them both crazy, or are they on the road to forever?
