Following on the success of the various Humble Bundles for DRM-free video games, the organization has just launched its first Humble eBook Bundle. It includes Pirate Cinema by Cory Doctorow, Pump Six by Paolo Bacigalupi, Zoo City by Lauren Beukes, Invasion by Mercedes Lackey, Stranger Things Happen, and Magic for Beginners, both by Kelly Link. If you choose to pay more than the average (about $11 at this writing), you also get Old Man's War by John Scalzi, and Signal to Noise, by Neil Gaiman and Dave McKean. The books are available in PDF, MOBI, and ePub formats, without DRM. As with all the Humble Bundles, you can choose how much you'd like to pay, and how the proceeds are split between any of the authors and/or among three charities.
