Horror/sci-fi fans, here you go... Scott Sigler's new and very well-reviewed thriller, Infected, can be downloaded for free via podcast (iTunes - Feed - Web site). Or you can get it in hardback for $16.47, which I'm not discouraging you from doing.
With the links above, you can download more free books from Sigler. But, I warn you that the books contain a good dose of graphic language.
