WWI book

I thought The Radetzky March was very interesting novel for the Austro-Hungarian Empire. It really gave a look at life in those days.

Be prepared to be alarmed at the thought of history repeating itself..

Storm of Steel by Ernst Junger. Young German soldiers account of the war. Dude basically had balls of steel.

Fought in the Somme, the battle of Arras, Passchendaele, Cambrai, and the final German Spring Offensive in 18. Was shot and wounded multiple times.

If you haven't listened to Dan Carlin's Blueprint for Armageddon 6 part podcast it's highly recommended, the best podcast I've ever listened to and every bit as long as a book.

And I'll second The Guns of August.

Another but very different is Mark Helprin's A Soldier of the Great War. It's fiction, and magical realism, and I really love the thing.

In addition to The Guns of August, A World Undone is fantastic.

Sleepwalkers by Christopher Clark is a great book about the build up to the war.
The First World War by John Keegan
Price if Glory Allistair Horne about Verdun

It's been a while since I've read this but I remember enjoying The Unknowns. It's a book about the pallbearers of the man who would be interred at the Tomb of the Unknown Solider.

It basically gives a cool bio of each individual as well as their specific experiences during WW1. If I recall, there was also a bit in there about how the body was chosen, how the tomb came to be etc.
