Two sisters. An unputdownable story.

Cee woke up on the shores of an abandoned island three years ago with no idea how she got there. Now eighteen, she lives in a shack with an ageing android, and a single memory: she has a sister, and she has to escape to find her.

From the safety of the eco-city floating above Earth, now decimated by natural disasters, sixteen-year-old Kasey mourns Cee whom she’s sure is dead. She too wants to escape: the eco-city is meant to be a sanctuary for people who want to save the planet, but its inhabitants are willing to do anything for refuge, even lie. Is Kasey ready to use technology to help Earth, even though it failed her sister?

Cee and Kasey think that what they know about each other and their world is true. Both are wrong.
