Innisfree—the wild and isolated land on Chappaquiddick Island where Josiah Monroe grew up—was the only place where he felt he belonged. When his parents make the painful decision to sell the land, the loss of Innisfree catapults the entire family into a spiral of disconnection. Josiah abandons the island in anger, seeking to redefine himself and reconcile his mixed Wampanoag and Irish heritage in a wider, more dangerous world marked by the turmoil of the Vietnam War and the cultural upheaval of the Sixties. His family struggles not only with Josiah’s alienation but also with the debilitating polio suffered by his sister, Izzy. At the same time, the new owner of Innisfree becomes a force driving them apart. Ultimately, it is the power and magic of the island itself and the bonds of family that call them back to one another.
