If you're into comic's you should definitely pick up the new Dark Horse comic : Dawn of the jedi which is realy AWESOME (be sure to pick up the #0 : introduction to the dawn of the jedi universe or something which explains the time era)
Have fun reading =)
OMG! I didn't even realise this was out. TY so much.
I'm also thinking Darth Bane books. Heard Drew Karpyshyn writes a good book
