Cheap, anthology of short stories with an endless possibility in scenery and plots. For me, this is on par with a Clive Cussler novel. You know what you get before you start. Not the best stuff, but never bad.
Fred Saberhagen Beserker Novels
The Berserker series of science fiction short stories by Fred Saberhagen (1930-2007) is a variety of space opera in which robotic self-replicating machines intend to destroy all organic life. These berserkers, a doomsday weapon left over from an interstellar war 50,000 years ago, are killer spaceships furnished with machine intelligence, operating from asteroid-sized berserker bases where they are capable of building more Berserkers and auxiliary machines. The name is a reference to the human “Berserkers”, warriors of Norse legend.
