A Man Called Ove

by Fredrik Backman, Sweden.
Ove, the world's grumpiest old man, has staunch principles, strict routines, and a short fuse. People think him bitter, and he thinks he is surrounded by idiots. Then his well-ordered existence is turned upside-down when an Iranian family moves into his neighborhood. Ove's journey back to the living has begun, and we're invited. Heartwarming.
