At Home by Bill Bryson. He goes through each room in his house and delves into the history of each. The kitchen, the hall, the bedroom, etc. and everything in them. Some people would probably assume it’s dull, but I love those little tidbits of history, and Bill Bryson is a master of educating while not getting dry.
Ignatius J. Reilly from A Confederacy of Dunces
Genuinely one of the most unique characters of all time. Utterly weird and utterly memorable. Any time I’m not feeling well, the first thing I do is blame my valve.
