Esk One is an ancillary, is a decade, is a ship and Breq is none of these any longer. Severed from conjunction with the AI that was the ship, The Justice of Toren, Breq is seeking justice of her own. But her past won’t leave her alone. The former Lieutenant Seivarden whom she rescues, as an after thought, becomes a burden. The memories that she’s forced to share with the owner of the only weapon that can guarantee her success cloud her resolve. Finally, the insecurity of the validity of her own desires make her question her mission. Can a mere part of the greater whole she once was find the vindication she desires?
