Sure. 'Birdsong' by Sebastian Faulks is a notable one. It weaves together the story of a present - day man researching his family's past in the war with the actual events during World War 1. The descriptions of the trenches and the relationships between soldiers are quite moving.
Well, 'Johnny Got His Gun' by Dalton Trumbo is a very powerful novel. It's about a young American soldier who is severely injured in the war, losing his limbs, eyes, ears and ability to speak. It's a harrowing exploration of the cost of war and a strong anti - war statement.
'Regeneration' by Pat Barker is excellent. It is set in a military hospital where soldiers are being treated for shell shock. It delves deep into the psychological trauma of war and how the medical staff tries to help the soldiers recover. It gives a very different perspective on the war compared to those focused mainly on the battlefields.
