What price would you pay for freedom? Return to the acclaimed dystopian world of the Key by New York Times bestselling author Kristin Cast, as two young rebels fight to determine their own worth and change the world along with themselves.

Safety comes with a price.

The Key Corporation has kept Westfall safe from pandemics for the last fifty years. But that’s not all they’ve done …

After discovering the shocking truth behind the Key Corporation, nurse Elodie and misfit Aiden have managed to escape in search of New Dawn—the stronghold for the Eos resistance movement. There, they can fight for a better world, one where everyone can make their own futures.

But things aren’t always as they seem, and as they navigate the tricky paths between perception and reality, freedom and fighting for survival, the two young rebels must discover who they can trust, even as they learn more about who they really are …

And change also comes at a cost.
