The title is a description, not a command. Tor is giving away free .pdfs of some of their titles, at the rate of one a week, and they’ll email them right to your own personal inbox, if only you ask. Not only that, there’s a contest involved. I’m signed up, of course, because if there’s anything I like more than a book, it’s a free book transmitted directly through the ether into my home.
And of course, there is also the Baen Free Library.
