It is 1940 when Peter Harding joins HM Submarine Shadow for his first tour of duty.

Shadow is not a happy ship, ruled by an overbearing, unlikeable commander. But Harding learns rapidly, and the fortunes of war dictate changes in both his and Shadow’s future.

From infiltrating the fjords of Occupied Norway to stalking U-boats on the Mediterranean convoy runs, Shadow becomes both hunter and hunted in the deadly undersea war. But as the price and pace of battle at sea and on land builds, Harding’s fate becomes ever more closely linked with Shadow – and with her crew.
