No Survivors: The U-Boat Series (The U-Boat Book #1)
Mutiny or murder. These were the stark choices that confronted Kapitan-Leutnant Konrad Bergman. To go against the discipline and training that had been instilled in him from his youth and disobey an order. Or to carry out the Fuehrer's command and destroy his own comrades in an act of cold-blooded premeditated murder.
As commander of a U-boat, Bergman had always greedily accepted his orders, lusting after each of his kills with the relentless energies of a primitive predator. Now the harsh realities of war were proving to be somewhat different from the romantic dreams of his youth. But it was too late to change his destiny now.
