This is both a "coming of age" story and a romance. The heroine has spent her life avoiding responsibility, and her summers at the family "resort," Chez Ducky, a big old house (with a couple of ramshackle cabins) on a second rate lake in Minnesota. The oldest woman in the family is, by default and family tradition, the one in charge of the family place. But Aunt Birgie doesn't want the responsibility either. She wants to maneuver the heroine, Mimi, into taking over. Chez Ducky is threatened by the discovery of the lake by the new rich, as exemplified by the Gigantic "lake house" built next door. In the opening, Birgie is trying to manipulate Mimi, who avoids her by deciding to go skinny-dipping in broad daylight. Except then her swimsuit is lost, so she decides to swim out through the lilypads/mud and sneak back to her cabin through the trees. Then she stumbles across a car--which seems to be abandoned, and while rifling the trunk (which is open) for a blanket as clothing, is startled by the driver who was changing a flat and out of sight. She takes him home with her, and he's absorbed into the vast clan, until they learn that he's the father of the guy who built the hated Gigantic monstrosity of a rich kid's house. Father/hero has no idea how to connect with his kid, but he's here to try yet again. Sounds convoluted, but it works. It's a quirky, funny book about family and growing up, and love and all sorts of great stuff. It's a good read. I liked it.
