Beautiful Ruins by Jess Walter
The story begins in 1962. On a rocky patch of the sun-drenched Italian coastline, a young innkeeper, chest-deep in daydreams, looks out over the incandescent waters of the Ligurian Sea and spies an apparition: a tall, thin woman, a vision in white, approaching him on a boat. She is an actress, he soon learns, an American starlet, and she is dying. And the story begins again today, half a world away, when an elderly Italian man shows up on a movie studio's back lot--searching for the mysterious woman he last saw at his hotel decades earlier. What unfolds is a dazzling, yet deeply human, roller coaster of a novel, spanning fifty years and nearly as many lives.
