Goodreads summary:
Imagine that you have two minds, sharing one body. You and your other self are closer than twins, better than friends. You have known each other forever.
Then imagine that people like you are hated and feared. That the government want to hunt you down and tear out your second soul, separating you from the person you love most in the world.
Now meet Eva and Addie.
They don’t have to imagine.
Throughout the book Eva and Addie go through many internal struggles and battles and I thought these were the highlights of the book. Eva's situation was really heartbreaking and frustrating. The writing was superb, capturing the trapped-in-a-cage helplessness of Eva as a lot of the time, Addie made the final decision of what they did. A little romance was thrown into the story which added another interesting concept to explore what with Eva and Addie sharing the same body but not the same feelings.
A compelling read and a promising start to the series!
