Just ordered a book that I'd read an online version of. It's a good story, although the online version really needed some competent editing. He's selling it now at http://lightsoutthebook.com/

The book's name is 'Lights Out' and is a TEOTWAWKI-style fantasy about what might happen if an EMP burst took out most of our technology.

I liked it enough to order it after reading it for free, so that should say something
