Patrick Rothfuss has just begun his second annual Heifer International fundraiser, which now has a name: Worldbuilders. If you donate you can get lots of cool prizes, most of which are sci-fi/fantasy books.
I was looking at the FAQ, and was happy to see the answer about the openness of Heifer’s financial numbers; less than 25% of the money donated is used for administration, which is great, and most of that “administration” money is used for fundraising. So please donate, and spread the word to anyone who might be interested. Thanks!
