Erich Maria Remarque did an excellent job of capturing the horrors of war in, All Quiet on the Western Front. The language used by the author is descriptive and graphic.
The author also portrayed how Post Traumatic Stress (known as shell shock at the time) effected the main character. While on leave, he was unable to connect with his family, exhibited signs of depersonalization, was depressed, and dealt with feelings of rage.
Reading the book was an eye-opening experience and I would recommend it.
