1. The Lord Of The Rings Trilogy, by J.R.R. Tolkien
2. The Hitchhiker's Guide To The Galaxy, by Douglas Adams (and the sequels. I still prefer So long, and thanks for all the fish
3. Ender's Game, by Orson Scott Card
4. The Dune Chronicles, by Frank Herbert - read the first one, back around the time the film came out (and despite not having seen the film yet), but no the rest.
5. A Song Of Ice And Fire Series, by George R. R. Martin
6. 1984, by George Orwell - at least, I'm pretty sure I've read it all the way through once.
7. Fahrenheit 451, by Ray Bradbury
8. The Foundation Trilogy, by Isaac Asimov - never properly read it, although I sort of dabbled with it in secondary school when the books were in the school library. I'd like to give it a proper read at some point.
9. Brave New World, by Aldous Huxley
10. American Gods, by Neil Gaiman
11. The Princess Bride, by William Goldman - I've seen the movie, if that counts..?
12. The Wheel Of Time Series, by Robert Jordan - no, but Sarah has.
13. Animal Farm, by George Orwell - as with 1984, I'm pretty sure I've read it all the way through, but couldn't quite put my finger on exactly when.

23. The Handmaid's Tale, by Margaret Atwood
24. The Dark Tower Series, by Stephen King

32. Watership Down, by Richard Adams - don't think I've ever finished it, despite having a copy of the book since probably before the film came out. As I'd have been about seven at the time, maybe that was the problem? It's definitely not a children's book.
33. Dragonflight, by Anne McCaffrey - no, but again, ask Sarah. She has a fair few Pern novels.
34. The Moon Is A Harsh Mistress, by Robert Heinlein

48. Neverwhere, by Neil Gaiman
49. Childhood's End, by Arthur C. Clarke

51. The Hyperion Cantos, by Dan Simmons
52. Stardust, by Neil Gaiman - no, but Sarah and I saw the film together, and she's got the novel.

54. World War Z, by Max Brooks
55. The Last Unicorn, by Peter S. Beagle
56. The Forever War, by Joe Haldeman

77. The Kushiel's Legacy Series, by Jacqueline Carey
78. The Dispossessed, by Ursula K. LeGuin
79. Something Wicked This Way Comes, by Ray Bradbury
80. Wicked, by Gregory Maguire - no, but this is in my pile of books to be read, having really enjoyed the musical back in January.
81. The Malazan Book Of The Fallen Series, by Steven Erikson
82. The Eyre Affair, by Jasper Fforde - no, but Fforde is an author I intend to check out at some time.

84. The Crystal Cave, by Mary Stewart - again, I think Sarah's got a copy of this.

86. The Codex Alera Series, by Jim Butcher - no, but I'd like to try his Dresden Files books.

92. Sunshine, by Robin McKinley

97. Doomsday Book, by Connie Willis - I've read one of her books, but I don't think it was this one.
98. Perdido Street Station, by China Mieville
99. The Xanth Series, by Piers Anthony - I borrowed one from a friend. Didn't think that much of it, I'm afraid...
100. The Space Trilogy, by C.S. Lewis - I read one of them (Perelandra, I think), but, erm, yeah. Bored me.
So...a few I've read - I make it 18, including ones where I've read one of a series but not the remainder, which isn't bad, but I've not read as much sci-fi/fantasy as I could. Although there are several I'd like to try (really, any of the Asimov/Wells/Verne that I've not read, I'd like to). I think I'll definitely be able to add a couple (Wicked and Stardust) to the list by the end of the year, and it'd be nice to check out Jasper Fforde's work too.
