Sherry's disappearance is an act of desperation by a small group of rebels in Donderi territory to force the people of the New Alliance in helping them win their freedom. Good thing for them, Sherry had already planned on doing just that. She cannot do it alone, and soon finds she doesn't have to as her faithful bodyguard arrives with the only other person capable of piloting the Killer Queen, Chicago. Along with several RG soldiers, they have been hitting the Donderi forces for several weeks just as Sherry comes back to herself and escapes the prison she finds herself in.
With more than half her force arriving in the Donda Prime system, they take control of the Donderi home world, but can they keep it, and will they have enough power to expand the New Alliance so far away from home?
