A Man Called Ove by Fredrik Backman (2015)

Original in Swedish came out in 2012. A Man Called Ove was heartwarming - took a while to warm to the curmudgeon, but ended really caring for him, even if I wouldn't want to live on his street. Not quite as funny and great as the 100 Year Old Man Who Climbed Out the Window, but some similar Scandinavian humor. 

Ove is a grumpy old man who lives by himself in a neighborhood that he patrols daily and expects things to be just so. Then a lively family moves in next door and starts by knocking over his mailbox. I won't say more - and let others have the book unfold as they read it. But it really made me think - when someone is grumpy and bitter, do I remember to ask why? There may well be a very good reason.
