Ever since the war ended, the United English Cityships have had equality. The rules are clear. You are born, you live and the day following your sixtieth birthday, you are sent off for your final sleep.

Lock is a firm believer in the system. It means that everyone is truly treated equally. It's only when she checks in an attendee who claims to be younger than her chip says that Lock starts to realise there may be someone gaming the system.

The problem is the corruption goes higher than Lock could even begin to imagine. As her belief in the world she lives in starts to crumble, Lock finds herself wanting justice for those who have gone before their time.

Can she do it? Or will they silence her before she can get the word out?
