With her father still in power, Frey must return home to Shreve on a secret mission, while her sister Rafi gathers an army against him.

Frey and Col must enter the lion's den to rescue Boss X, but Frey's father has eyes everywhere. Even with her camo-surged face and a new identity, every minute risks discovery and disaster.

In this city under surveillance, nothing is what it seems on the surface. How will she know who to trust?

The riveting third instalment in the New York Times bestselling Impostors series.
