The final installment sees our characters with increasingly more difficult obstacles and life decisions. The changes in the Republic start to show and we get to see where the Republic is in the great scheme of things.
And just as it happens in real life we get to see how our characters had naive outlook on life based on their rather narrow experience, and how they get more mature in the process of unraveling.

By the end of the book you will be so emotionally invested in the characters that you'll find yourself clutching the book and yelling or crying or laughing. It is steadily building up to the roller coaster at the end.
