Under the Arctic ice pack, Mac and team commandeer an abandoned Soviet Alfa-Class submarine. Naturally, the Russians want it back."I especially love Borysko, the warrior Orca who comes to the rescue when hungry polar bears and hostile Spetsnaz divers attack Mac's team." —Professor John B. Rosenman, Norfolk State University When Mac McDowell's saturation dive team captures an abandoned fully automated Alfa-Class Soviet submarine, his divers and the crew of USS Teuthis attempt to pilot their prize under the Arctic ice cover to the U.S. East Coast. They must evade or confront other Soviet subs trying to recover the Alfa—or sink it. Breathtaking deep-sea clashes erupt under the ice, including hand-to-hand combat with Soviet Morskoy Spetsnaz divers. When polar bears attack Mac's divers, they survive with the help of a 5-ton Orca. Mac's mission: Survive long enough to reach friendly waters and deliver the captured Soviet submarine.
