Book excerpt: In 1942 alone, German U-Boats sank almost four million gross registered tons of Allied ships convoying goods and war supplies to the war ravaged European continent, Britain and North Africa. That same year, 17-year-old Jimmy Kindall leaves his small Mississippi town to join the Merchant Marine. He soon discovers that supplying the troops in unprotected waters exposes him to some of the fiercest battles in WWII.
