A quick note: If you're not already familiar with it, Tor.com is a web site dedicated to "science fiction, fantasy, and all the things that interest SF and fantasy readers." And, among other things, the site regularly publishes original sci-fi stories. To celebrate its 5th birthday, Tor has decided to assemble the last five years of its original fiction and make it available as downloadable ebook files. You will need to register with the site beforehand, and then you can download the texts in various formats -- PDF, Mobi, and ePub -- all of which can be loaded onto ebook readers. And, yes, it's all free.
If you're a sci-fan, we'd encourage you to see our post from earlier this week, 100 Great Sci-Fi Stories by Women Writers and then some of the great related material below.
