Told through short, poetic chapters, this sweeping love story follows two teenagers whose lives—and the lives of everyone in their quiet New England town—are forever altered by a shocking transformation. In a New England spa town, now long past its Victorian heyday, there still stand twelve pools, sourced by a single hot spring. The people of the town swim there every day. After school, they swim. After dinner. For playdates. For dates. Legend has it, one day long ago, people who bathed in the pools turned into birds. But that is just a tale.
