The Humble ebook Bundle II is still going apace, despite not selling quite as many as the average gaming bundle. However now, if you pay above the average, you'll get a few extra ebooks added to your library, including volume 0 of the XKCD comics.
The basic stack of ebooks you get access to are: Little Brother by Cory Doctorow, Boneshaker by Cheris Priest, Spin by Robert Wilson and Shards of Honor by Louis Bujold. The's just the start though. Paying above that lofty $10 average and you'll not only get the aforementioned digital comic collection, but you'll also get Wil Wheaton's Just a Geek, Peter Beagle's The Last Unicorn, Signal to Noise by Neil Gaiman and Dave McKean, Holly Black's Poison Eaters and Other Stories and Machine of Death, by Ryan North, Matthew Bennardo and David Malki.
If you're struggling for reading material, this lot should sort you out for a while.
Most if not all of these books have high review ratings on both Goodreads and Amazon, so it'll probably be difficult to go wrong with any of these, even if some will appeal more than others.
KitGuru Says: If you guys kick in a few dollars to this and hit me up on Facebook or Twitter, I'll send you over a free copy of my ebook too. Supporting authors is really important, especially through great initiatives like this.
