Scifi lovers, check out Overclocked: Stories of the Future Present. It’s some great “hard sf” from the man who is truly becoming the next great science fiction author, Cory Doctorow. Also it’s free.
In this volume, he steps partway back from his usual close-to-absurd-but-just-believable style and collects a few of his pieces that follow more traditional motifs. He goes so far as to name them after classics as in “I, Robot”. He uses this backdrop to add modern ideas including his own views, interpretations, and visions of intellectual property, gaming, and even religion. Also it’s free.
Seriously, if nothing else read the 2 page “Printcrime” . You really owe it to yourself, it’s profound. Also it’s free.
I bought the book since I basically love to read sci fi while curled up and falling a sleep (I have since I was a child), but if you’re not sure yet, read them for free online, or print them out, because…it’s free.
PS: I began a Wikipedia article on the collection: here.
