Refitted and rushed back into battle, half her crew raw recruits, U-451 is on the prowl again. Captain Baldur Wolz — the grizzled veteran they call Sea Wolf — will need all his commander’s skills to keep his ship on her course of slaughter. And he must save his killing machine’s deadliest weapons for the biggest targets: American tankers risking the Atlantic crossing to beleaguered Britain. But the pressure begins to rise inside the U-boat’s steel shell. Wolz and his crew have been lucky too long — now they’re living on borrowed time …

          SHARK TRAP is the eighth in the gripping series of novels about the U-boat war waged with grim ferocity in the bitter depths of the world’s oceans.
