Query: Very Good Novel

Based on a WWI myth about deserters living beneath the savaged ground of no man's land, this is a very well written and often gripping novel which is required reading for anyone with an interest in the First World War. Hill creates realistic characters with depth and feeling and motivations that challenge the reader to understand their sometimes brutal actions. The situations are most often within the realm of belief and the philosophical debates subtle and profound. An overlooked and underrated literary effort to explore the insanity of war in a fresh way that rates as an overall success.
