For Whom the Bell Tolls

I am currently in the middle of a great book, For Whom the Bell Tolls.  The book takes place during the Spanish Civil War.  The book's main protagonist is Robert Jordan.  Robert Jordan is an American dynamiter, who is assigned to blow up a bridge.  He is attached to an anti-fascist guerrilla unit.  In the guerrilla unit he meets and falls in love with a girl named María.  I am roughly one forth into the book and the author, Ernest Hemingway, has done a great job developing major characters.  He has given some characters great and thorough back stories.  Despite this, many secondary characters lack development, thus far.  All the characters in the book have exceedingly genuine voices and seem very natural and real. The author does a great job at writing vividly and does a great job at capturing emotion. The book's plot has been slow and not very exiting. I hope the book will become more exiting deeper into the book, but I don't think it will be necessary. Due to the slow plot, the author has had time to vividly describe every scene; the author would not be able to do that if he had a quick and suspenseful plot.  Overall, I love this book and can't wait to read even more of it.  I would recommend it to anybody who wants to read a descriptive and great book.
