Pay what you want to take home the Humble eBook Bundle and if you pay more than average then you’ll also get to download Neil Gaiman and Dave McKean’s Signal to Noise as well as John Scalzi’s Old Man’s War.
For just a single dollar (money gets split between the authors and charity) you could have Cory Doctorow’s Pirate Cinema, Paolo Bacigalupi’s Pump Six, Lauren Beukes’ Zoo City, Mercedes Lackey’s Invasion, Kelly Link’s Stranger Things Happen and Magic for Beginners.
Bundles work to support charity and, in this case, promote reading. The books are DRM free and multi-format so will work on devices like Kindles and iPads.
