Velocity Wrachant, owner and captain of the merchant starship Susan Calvin, is broke and stranded on a Drift station, when she is offered what seems like a simple job: to escort young Bront Ikeda into Republic space and help her retrieve several bonded-labor children.

While Velocity is tempted by the fee Bront offers - which is enough to clear her debts - she also knows that Ikeda House, a powerful Combine, just had a major coup; and both she and her crew suspect the story they're being told by the Combine child is not the whole story.

Velocity takes the gig, but it takes her into the heart of Combine territory, a place she fled almost twenty years earlier. What is the price she and her shipmates may end up paying for this job?
