The stunningly written third book in Kat Zhang's heart-stopping Hybrid Trilogy.

All Eva ever wanted was the chance to be herself. But in the Americas, to be hybrid - to share your body with a second soul - is not tolerated past childhood. Now Eva and Addie, her sister soul, are constantly on the move, hiding from the officials who seek to capture them. But the tide is changing. A revolution is brewing, and people are starting to question the hybrids' mistreatment.

Eva and Addie are asked to go undercover and film these horrors, so they can be exposed - as they walk into danger, they cling to each other and the hope of a better future. But the price they might pay is higher than they ever could have imagined.
