The men of the Dorsai were the finest fighting soldiers in the universe, mercenary troops without equal.

Their talents were devastatingly employed on Kultis, where a bloody little war raged between the Western Alliance and Eastern Coalition. But not even the Dorsai could anticipate the dramatic effect of Cletus Grahame's brilliant mind and the galaxy-shaking theory he called The Tactics of Mistake.

This first book in the Dorsai sequence is the story of how Cletus Grahame risked his life, the fate of three worlds, and ultimately the whole of the Dorsai to prove that a mistake may remake worlds. A classic of science fiction.
