American War by Omar El Akkad

What can I say about American War by Omar El Akkad?  It's set in the future around 2075.  There is an American civil war going on.  Global warming has submerged a large portion of our country.  The concept intrigued me.  I felt as though the author could have done so much with the story.  However, he didn't really.  It was basically just a story of revenge.  Revenge that begets revenge to be more specific.  The ending was especially disappointing to me.  I just really saw no purpose to the book other than the revenge angle.  It was annoying for me, but if you like a good revenge story, then maybe give this one a try.  For me, it was a 2 out of 5 stars.
