The Absolutist

I am starting The Absolutist by John Boyne today.  This is the first book I won from goodreads.  I read The Boy in the Striped Pajamas by Boyne last year and really liked it.  The Absolutist is the story of a soldier named Tristan who is taking letters back to the sister of a man named Will that he fought alongside in WWI.  Tristan has a secret that he is finally willing to share when he returns the letters.  I'm really curious to see what happened between these men during the war.
