One dark summer dawn, at the very moment that an enormous monster dies in Lake Glimmerglass, twenty-eight-year-old Willie Upton returns pregnant and miserable to her hometown of Templeton, N.Y. Willie is a descendant of the creator of the town, Marmaduke Temple, and she expects to be able to hide in the place that has been home to her family for centuries. But the monster changes the fabric of the village, and Willie's mother, Vivienne, has a surprise for the girl that will send Willie careening through her family's history to dig up clues about her heritage. Spanning two centuries and based on Lauren’s hometown of Cooperstown, New York., the story is told through two centuries of voices, from Templeton ghosts to residents, masters to servants, natives to interlopers, and historical figures to literary characters.
