Peter Watts makes Blindsight (as well as the three Rifters novels) freely downloadable from his website. Read or download Blindsight at
http://www.rifters.com/real/Blindsight.htm. And for the Rifters finale (Behemoth) he doesn't split it into two books like his publisher at the time made him do (for probably legitimate publishing concerns).
But then donate to him or buy the book somewhere so he gets some money for his work
