Deter and Lincoln are both on board the Sanctum ship the White Swan. It is luxurious and reminds Deter of her past life in New York. Lincoln has the best medical care and they have made new friends, but as time goes on she begins to wonder, are they guests or prisoners?

In New York, Angus and Roller are building an army. They have limited resources and as the Establishment hold over the people tightens, they are forced to shelter underground. As food supplies and morale start to drop, they realise that time is running out.

Treading a fine line within her new role at the Sanctum, Amery juggles loyalties in order to keep Deter safe.

The battle for power must be decided.
