"...Humble Bundles, collections of games and books sold at a price determined by the purchaser and with a portion of the price going towards charity and the rest split between the creators"
So you get these ebooks at very low prices, help us out and help out a charity. Our book is THE MINAMATA STORY, plus there are lots of other good books in the bundle, including JAPAN FROM ANIME TO ZEN from David Watts Barton and THE ART OF SETTING STONES from Marc Peter Keane
Nice.
