Imagine that you have a twin somewhere out there. A twin you've never met, a twin who acts nothing like you, a twin who wants to kill you, a twin that you must kill. Dualed is about a girl named West, and like everybody else in this futuristic world, she has an Alt. She has been training with her siblings to fight her Alt when her day comes. And as prepared as she is, she is not ready for the fact that her Alt has hired a striker to kill her.
This book is pretty violent--definitely for the people who like the Hunger Games books and other dystopian novels. I would reccomed this for teens and up.
