Go to Stephenie Meyer's official website
link . Click the Twilight Series ícone and pick the Midnight Sun ícone 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 mais detailed than Bella's pov in Twilight. In a nutshell, Midnight Sun is AWESOME!
++and i forgot to add something. But if you are seriously against piracy, don't do this.(Don't do this until you are seriously in desperation) You can download the printable version of MS from some website called 4shared. That was what some of my friends did and it worked.
