Didn't realize Humble Bundles did books. Apparently this is the second time. This current Bundle is SFWA approved.
- Cory Doctorow - Little Brother
- Cherie Priest - Boneshaker
- Robert Charles Wilson - Spin
- Lois McMaster Bujold - Shards of Honor
- Peter Beagle - The Last Unicorn
- Wil Wheaton - Just a Geek
The last two in bold are the ones you have to pay more than the average to get. The other four you get for whatever you want to pay. Buy books! Support charities! Bundle!
