(Context, and a sampling of available works, here.)
Following in the footsteps of Peter Watts, whose decision to make his novel Blindsight available online under a Creative Commons License may very well have been a major factor in getting said novel on the shortlist for this year's Hugo, fellow nominee Michael F. Flynn is allowing readers to download his novel Eifelheim (PDF). Flynn is also nominated this year for the novelette "Dawn, Sunset, and the Colours of the Earth", which I greatly enjoyed, and as it turns out he is also the author of a very fine piece from the 2005 Hugo ballot, "The Clapping Hands of God." All that, plus an interesting premise--a first contact story set in 14th century Europe--makes me quite eager to give Eifelheim a try. (Link via SF Signal.)
In unrelated news, and coming as a surprise to, I suspect, absolutely nobody, Drive has been cancelled.
