To Kill the Leopard — Theodore Taylor

Aboard the oil tanker SS Galveston, American merchant mariner Sully Jordan has joined the dash across the North Atlantic to a besieged Great Britain. Beneath the surface of those same chill waters Kapitanleutnant Horst Kammerer prowls with U-122 -- the seemingly invincible U-boat with snarling leopards painted on its conning tower. As a world war of countless battles rages, these two brave men face off in an unforgettable clash of stealth, treachery, and explosive force.

The lines of fire have been drawn in distant capitals and countrysides, determined by the intricate espionage network of the French resistance, the psychological ploys of the British command, the strategic expediency of the American government, and the growing menace of the Nazi war machine. It is a war that all sides are prepared to wage at any cost. But it is in the ice and fire of a black, brutal ocean that the price will be paid -- as two like-hearted men match wits in a relentless duel to the death at sea.
