Saw this on GearDiary
today. Six eBooks by Cory Doctrow, Mercedes Lackey, Kelly Link, Paulo Bacigalupi and Lauren Beukes. If you beat the minimum price, you also get Signal-to-Noise by Neil Gaiman and Dave McKean, along with "Old Man's War" by John Scalzi.
Very sweet deal. I'm surprised I didn't already see a post in the news forums about it. In PDF, ePub,and Mobi format too.
