That book meme:

1. One book that changed your life
Illusions, Adventures of a Reluctant Messiah by Richard Bach.
This book taught me that I'm not the only one who's mind works the way it does, and let me know it was good to encourage those modes of thought, rather than to stifle them. Honorable mention has to go to all the books by Madeline L'Engle I read as a kid, for the same reasons.

 2. One book you have read more than once

Believe it or not, the only book I can recall reading more than once is The Amityville Horror by Jay Anson. Both times I read this, I was still a teenager, and it was because this book scared me more than any other book I've read. Could be because I was just a teenager, though.

 3. One book you would want on a desert island 
Survive on a Desert Island by Claire Llewellyn.  Duh.

4. One book that made you laugh

Mostly Harmless  by Douglas Adams. It's hard to pick just one from this series, so I'll pick the one that got me in trouble for laughing out loud during the middle of an anthropology class in college. Don't ask me why I was reading Douglas Adams during an anthropology class.

 5. One book that made you cry
I don't know that one ever has. This, in itself, is reason enough to cry.

 6. One book you wish had been written

An entire series of novels set in the “Armada” universe that my friends and I created in high school and college.

 7. One book you wish had never had been written
The DaVinci Code by Dan Brown. The thing that annoys me about this book is that it took a controversial and fringe topic and made it hip. This resulted in it's being marginalized as fodder for the masses. It also set off a flood of “___ Code” titled books. Fads are dumb.

 8. One book you are currently reading
I'm embarrassed to admit that I still haven't finished The Strange Adventures of Rangergirl by Tim Pratt. It is no fault of the book's, just my own odd schedule and procrastination. My reading habits have slipped so much in recent years as to be shameful.

 9. One book you have been meaning to read
Baudolino by Umberto Eco. I've never met an Eco book I didn't enjoy, and that didn't expand my vocabulary and language skills.
