Okay let's get the bad stuff out of the way. To start things off, many times throughout the book it feels a bit slow. I find myself trying to read a part of the book, hoping that something exhilarating will happen, but it turns out to be slow. Following that, sometimes things felt the opposite and felt rushed. At some points of the book, I feel like some plot twists/reveals were forced into happening and being revealed. I would think to myself that it's a bit cliche. But otherwise, there's nothing else that really bothers me.
Now the neutral/mixed emotions. Sometimes the transitions are very good; making the audience know another character's POV at the time of an event. Other times... well it's a little dull. For example, one scene you'd be at an action paced-fight, the other, you'd be having a conversation. But yeah this is the only neutral/mixed emotion factor.
Now the amazing stuff. The characters are absolutely amazing, the plot is amazing, and the action-paced scenes are amazing. I cannot use words to describe how much I love Neal Shusterman's unique way of writing. The way that the characters interact with the world around them, and overcome the problems and struggles put before them really draws you in, and they dynamic between the characters themselves is also amazing. Really love it!
