My Grandmother Asked Me to Tell You She's Sorry by Fredrik Backman (2015)

Another delightful book from Backman, author of A Man Called Ove. This too builds slowly and then magically blooms into a heartwarming story of humanity.

Elsa is a 7 year old girl, who loves books and comics and is very bright, though she doesn't have friends. Her parents are divorced, her mother is busy with her career, so spends a lot of time with her grandmother. Grandma was a doctor saving lives around the world, is still constantly up for adventures and tells Elsa fairy tales - often based on real people. When grandma dies, she leaves Elsa a puzzle - envelopes she has to hand out to different people - but one at a time, so she gets to know them, and finds out how they were tied to grandma. Plus grandma has asked them all to watch over her. We rarely know the secrets of the individuals around us, what is behind the slick or weird exteriors. When you find out, their appearance and actions make sense. This was just a very feel-good book.
