24 Hour Read-a-Thon

I have signed up for Dewey's 24 Hour Read-a-Thon.

This means that, as the "24 hour" part of the read-a-thon's name implies, I will read for a solid 24 hour period starting at 2 AM EST on April 18th, 2009 and end at 2 AM the following morning (that's how a 24 hour period of time works).

Yes, I expect to stop reading for those pesky survival habits like eating and using the restroom; however, I have no intention of letting a single moment pass without the words of some book or another stimulating my brain. This will be accomplished through audiobooks. I will read until it's not possible to read, at which point I will switch to an audiobook and carry on until I can read again. This way I can start out reading at home, walk to Central Park or something, and resume reading there.

I can't wait!

Any suggestions for books?
