I read your OP and A Man Called Ove sprang to mind - spot on, roses ! I've given copies to several friends and recommended it to others (differing ages, both sexes) and without exception everyone has loved it as much as I.
An old favourite is Diary of a Nobody by George and Weedon Grossmith - very funny diary of a rather buttoned-up chap who writes about his family and friends.
