Name your price for Little Brother by Cory Doctorow, Boneshaker by Cherie Priest, Spin by Robert Charles Wilson, and Shards of Honor by Lois McMaster Bujold. Pay more than the average and you’ll also receive The Last Unicorn: Deluxe Edition by Peter Beagle and Just a Geek by Wil Wheaton!
This is a really awesome idea, unfortunately I have no interest in reading any of those books except the one I've already read. Also, at least one of them is available for free on the author's own personal site.
Four new books added for those who beat the average (currently $9.74): - xkcd: volume 0 (Randall Munroe) - Signal to Noise (Neil Gaiman & David McKean) - The Poison Eaters and Other Stories (Holly Black) - Machine of Death (Ryan North, Matthew Bennardo, and David Malki !)
I read the first Machine of Death anthology and it was really good! The second, This Is How You Die, is coming out this Tuesday and they're gunning for the New York Times bestseller list. I will buy it and you should buy it too.
