But the warrior spirit of the Dorsai does not, cannot, reside solely in the men of that race - for when the Dorsai go to fight wars on distant planets, it is the women who remain behind to defend their world and their future. The home planet of the Dorsai has never fallen to any invader, although many have tried...

Now the revolution had erupted, and the men once trained by the Dorsai bore arms against them.
