In Stargirl, what's the main conflict and how is it resolved?

The
original question had to be edited.  I would suggest that the main conflict in the novel is how
to navigate social assimilation in the high school setting.  This becomes critically important
forand Leo.  Both of them are impacted by this conflict in different ways.  Leo's reaction to it
is something that he does not fully understand until later on in his life.
