I don’t do as much re-reading of fiction as I used to, mainly because there are so many books out there I want a chance to read and already feel as it I don’t have enough time.:) When I was young, I re-read Harriet the Spy, The Westing Game, and all of the Encyclopedia Brown books over and over again. I also read the A Wrinkle in Time trilogy a few times.
When I’m feeling sick or low, I re-read the Discworld books. They are always a good pick me up. I remember re-reading the Sevenwaters Trilogy (Juliet Marillier) and Kushiel’s Dart over again because I really like the scenery, the characters, the lush worlds that were created. I do read Thomas Ligotti’s short stories, Ted Chiang’s short stories and Joan Didion’s classic Slouching Towards Bethlehem. There is also a Junichi Saga who has two great non-fiction books I’ve re-read several times Memoirs of Silk and Straw and Confessions of a Yakuza. If you wonder about life in Japan, particularly in the era when it changed rapidly, these are both great.
