Go to Stephenie Meyer's official website
link . Click the Twilight Series icone and pick the Midnight Sun icone on the left
link .You'll need Adobe Reader to download MS. There's only 12 chapters in Midnight Sun though but I really prefer to read from Edward's pov. I've already read it and i think it's definitely plus detailed than Bella's pov in Twilight. In a nutshell, Midnight Sun is AWESOME!
++and i forgot to add something. But if toi are seriously against piracy, don't do this.(Don't do this until toi are seriously in desperation) toi can download the printable version of MS from some website called 4shared. That was what some of my Friends did and it worked.
