No one man rules the Dorsai, but their mastery of the arts of war has made them the most valuable mercenaries in the human universe. Dorsai! is the saga of Donal Graeme, the uniquely talented Dorsai who will change their future forever. The Spirit of Dorsai, written two decades later, is Dickson's great novel of the women of the Dorsai -- in particular, the unconquerable Amanda Morgan.
