David Wellington has several ebooks available to read online or as iPod downloads. So far I've only read Monster Island, a great zombie survival book with a few twists to the genre.
If like me you don't have an iPod (weird I know) with a bit of patience you can use Windows WordPad to join the iPod notes into a text file, allowing conversion to your reader of choice (I just opened the file I made in iSilo) I hope the author doesn't mind.
