Amazon.com description: Product Description: Long, long ago...two alien races fought a war of extinction. All that is left of either of them are the Berserkers: vast, thinking, space-faring, killer machines whose sole purpose is to destroy all living things. For the first time in all of their history, they have met a life form that has a chance of stopping them. In the cold reaches of space, the Berserkers seize a floating laboratory full of human germ-plasm-stored for retrieval and growth in a future colonization project. But the ship contains millions of human lives. Why are the Berserkers not destroying them? And will the human pursuers manage to find the missing lab, defeat the Berserkers, and save the nascent lives? A major Berserker novel - one of Saberhagen's finest - with one hell of a surprise up its sleeve. In addition to the enormously popular Berserker series, Fred Saberhagen is the author of the bestselling Books of Swords and Lost Swords, as well as the chilling adventures (including A Question of Time) of the gentleman known as Dracula. He is one of the most popular writers in America today.
