It's the summer of 1989. Jack McGuinn is a dockporter, transporting tourists’ luggage, piled high in the basket of his bike on Mackinac Island, Michigan, a tiny summer resort where cars are outlawed and pedal-power rules. He’s got the season wired tight: a family cottage on the bluff, a dream job, and a loyal crew of hell-raising, tip-hustling buddies. When his old friend-turned bitter rival challenges him to ride a record-setting load, he takes the bet and soon realizes he’s not just carrying suitcases, he’s carrying the future of the island, which is about to be paved over for profit.
With the help of his pals on the dock and the love of a romantic, free-spirited Irish cellist named Erin, Jack digs deep to discover skills he didn't know he had. The Dockporter is an offbeat, nostalgic coming-of age-story that appeals anyone who ever had a summer job.
