Ove is a curmudgeon - he has strong principles, strict routines and a really short fuse...Behind the cranky exterior is a story and a sadness...and a character you won't forget. Perfect writing and extraordinary characters...
VINEGAR GIRL by Anne Tyler is my other recommdation. It's a screwball comedy of manners ...a contemporary retelling of the Taming of the Shrew. It has all the requisite Tyler trademarks including flawed characters, and fabulous prose. ( See a letter from Anne Tyler in an earlier post)
