Kate Laumer's popular saga of Bolo continues. Driven by a restless electronic brain programmed to deny the possibility of defeat itself, the giant robot tanks known as the Bolo were virtually indestructible and almost invincible. Their artificial intelligence was created to selflessly serve and protect people throughout the galaxy. Each Bolo was a revived idea of a knight without fear or reproach, and was often far nobler than the men who gave him orders. Now David Weber, the famous author of the Honor Harrington series, will continue the story of Bolo with four short stories, one of which is published for the first time. One Bolo is brought to the limit by the very people he is obliged to protect. The other must decide whether to carry out the order given to him to commit genocide. A third must track down another of the same, but with a damaged brain, and save two children, whom the deranged Bolo protects from a non-existent enemy. And finally a bonus! Written by David Weber, the official technical history of Bolo.
