The Unbecoming of Mara Dyer - Michelle Hodkin

It was confusing, until it wasn't. You knew something was off with Mara Dyer but the rational part of your brain tries to explain it away.

Until Noah reveals his secret. 

I LOVED this book. I am very happy I have the second to start straight away AND have the third preordered. 

I like a story that keeps me guessing.
