Seriously?... I mean All Quiet On The Western Front is one of the most famous novels and films of the 20th Century.
Needless to say I have a copy. It's by German author Erich Maria Reamrque who wrote it in the 1930s after his own WWI experiences as a soldier. It was also one of the books not surpisingly burnt by Hitler.
It's a modern classic and one of the best books written about WWI, although for that Title you have to look at Ernst Junger's Storm Of Steel, which I've also got.
As it became so popular overtime, you are correct in that the expression All Quiet On The Western Front has been integrated into the common vernacular to imply "all is calm" sometimes in a sarcastic mode e.g. on the "homefront".
