As for your database design - my only suggestion would be to seriously consider if you actually need the 'Story' model. IMHO, the following would be a better design for your app:
class Chapter(meta.Model):
source = meta.ForeignKey('self', null=True, blank=True)
This establishes that every chapter has a link from a source chapter. You can get the starting chapter by searching for the chapter for which the source is None:
starting_chapter = Chapter.get_object(source__isnull=True)
This would also act as a workaround, because ForeignKey on self works in 0.91.

Trying to make a "choose your own adventure" like application so
chapters don't have an "order" but knowing the starting chapter is
required. I can't figure out how to define the model.
class Story(meta.Model):
start_chapter = meta.OneToOneField(Chapter) #Chapter not defined yet
class Chapter(meta.Model):
story = meta.ForeignKey(Story)
