Death Dive — J.D. Cameron

U.S.S. Liberator -- sailing the oceans of a nuclear-ravaged world on the most dangerous mission of all... survival!

A radio call for help has reached the U.S.S. Liberator from the shattered metropolis of New York. Two families have somehow managed to emerge unscathed from the fire and devastation of nuclear Armageddon. But rescuing them may prove an impossible task. For thousands of radiation-crazed "white shirts" have arisen from the ruins of the once-great city for one final, savage assault on the desperate survivors' stronghold -- trapping Tom Donovan and his brave crew in the murderous center of an unrelenting reign of zombie terror.
