Douglas Adam's The Ultimate Hitchhiker's Guide. It's all his Hitchhiker's Guide novels in one giant book (about 1,000 pages). I've read it more than three times in the past few years. I tell people it's my bible and it never fails to put me in a great mood.
+1. That thing is just so full of all kinds of goodness. Did you ever read Last Chance To See
? I'm re-reading it again now, and it's been long enough since last time that I'm floored by Adams' superb writing all over again.
I also read The Lord of the Rings
once every few years, The Player of Games
by Iain Banks is a favorite re-reader, I'm pretty sure I'm about to read the entire Baroque Cycle
by Neal Stephenson again soon, and Drei Kameraden
by Remarque is a nice one that I always keep handy. There must be more, but I can't recall any more at the moment. Also, I'm too ashamed to confess that I've re-read Timothy Zahn's Thrawn trilogy
more than once, so I certainly won't mention that
A nice, summery white tea today, called First Love and recommended to me by Victoria on this forum years ago. It has become a solid favorite and re-drinker.
