A moving portrait of an elderly man's struggle to hold on to his most precious memories, from the internationally bestselling author of A Man Called Ove Grandpa and Noah are sitting on a bench in a square that gets smaller every day. The square is both strange and familiar, full of their lives' odds and ends. Here they share jokes, discuss their love of mathematics and Grandpa recalls falling in love with his wife, and how he dreads the day when he won't remember her. Sometimes Grandpa sits on the bench next to Ted, Noah's father, who prefers writing and playing guitar. They're very different, but bonded by their love of Noah. Grandpa, Grandma, Ted, and Noah all meet in this space that is growing increasingly dimmer and more confusing. And here is where they will learn to say goodbye.
