I just (last night) finished reading Kelly Link's Stranger Things Happen, and, having fallen quite a bit in love with it, was thinking about ordering another of her books today, and investigating Small Beer Press a little further.
I hadn't gotten around to it yet when I found this link (on bookslut) to a free download of a whole book from Small Beer Press. Nicely timed, magic internets.
Also, it turns out you can download the Kelly Link book, too. And you should. Because it's excellent.
