A Farewell to Arms is absolutely worth reading. It is the story of how war costs people their humanity, and how temporary all things might be. Hemingway is known for being a "plain" writer who puts great meaning in each word, and this is very clear in this book. It could be a challenging book for younger or infrequent readers, to follow the various themes, but it is absolutely worth the effort. The protagonist is made to experience war and Italy at the behest of others, it is the story of a person struggling for autonomy and the significance of choice.
