The Chronicles of Nick Theme

In The Chronicles of Nick the main character endures more in the first book than Katniss of The Hunger Games does in her entire series.  This is because the main character Nick, is thrown into a chaotic world.  One that he doesn't understand and doesn't want.

     One of the main themes in The Chronicles of Nick is survival.  This is because Nick is a Malachi and almost every preternatural being is trying to kill or capture him.  Plus his dad is a super-powered psychopath, not the best of parents. . .

     Another theme in The Chronicles of Nick besides survival is the loss of innocence.  Nick is taken from his "normal" world and forced to mature into an adult.  He really doesn't have a choice in the matter either.  Either he takes on the burden of him being born of evil, or he gets consumed by it.

     A second series that has these themes is the Inheritance Cycle.  In the beginning of the Inheritance cycle the main character Eragon finds a stone that turns out to be a dragon egg.  The very same dragon egg that the empire has been looking for for a long time.  When the Empire finds out that Eragon has the egg they immediately try to kill him.  From that point on Eragon is attempting to survive the Empires wrath.

The Inheritance Cycle  also features the loss of innocence.  When the stone Eragon finds turns out to be a dragon egg and hatches Eragon must take care of it and hide it from everyone -- including those he loves.  Once the empire finds out that Eragon has a dragon he must run for his life.  And in the process lose all of his childhood comfort

Because Nick got thrown into a strange and chaotic world where everyone wants him dead I think that the themes of

The Chronicles of Nick are survival and loss of innocence.
