Being Jenna and Julien trash, of course, that led me to this website but - before original members get too mad at me - I've always had a big boner for choose your own adventure stories.
That being said, does anyone have any recommendations? I'm a 20 something girl with a fucked up, dark sense of humor and tremendous ADHD.
Welcome to the site.
Try anything action-packed I guess. Madglee's Mommy (the one featured in the Modern section) is always a welcome use of time, and it is pretty dark while still being heavily choice-based and fun.
