World War I from a different point of view

Interesting that the book War Horse by Michael Morpurgo is aimed at younger (3rd to 6th grade) readers, but the recently released movie is for viewers who are older.  The book is told from the point of view of Joey, a beautiful red bay horse.  Joey is sold at a young age to a farmer who has little use for him. Fortunately, the farmer's son Albert is a sensitive young boy who takes wonderful care of Joey, and the two become very close.  But they wonder if they'll ever meet again, when World War I breaks out and Albert's father sells Joey to the army.  Soon Joey is in the trenches in France: pulling guns, hauling ambulance wagons, and witnessing the horrors of war.  Soldiers from both sides share their thoughts with Joey; not too surprisingly, these thoughts are quite similar and express the anti-war message the book is designed to deliver.  There are some sad parts, but overall the book is a good choice for fans of horses or historical fiction.
