there are three main paths, depending on if you hang out with bell, Heidi or gregg. The ending can also change too, but that depends a lot on what you do in the story :) I'd say the three routes should get most of the games content out of the way!

Well, from a glance 'The King in Yellow' by comes to mind :_D
Which i honestly can reccomend, good book.
