Oisâin Mahoney is an American Army vet in his 70s who is asked to lead a group of young grand-nieces and grand-nephews on a walk through the hills of California's Central Coast. Walking toward a setting sun, their destination is a place called The Museum of Rain, which may or may not still exist, and whose origin and meaning are elusive to all. In one of his most elegiac stories, Eggers gives us a beautiful testament to family, memory, and what we leave behind.
