Alright, so I have seen this book on goodreads for quite some time, but I had never actually decided to go ahead and read it, as it seemed more of a child book then a teen book. However, I decided to finally to pick it up and read the inside flap. 
 Bam! After reading the flap, I was still a bit hesitant, but I finally decided to read it. Wow, It was amazing. I loved, loved the book. Ren and Kelsey are amazing. The action and Kelsey's internal voice just made me fall in love with the book. I recommend it for everyone because it is just that kick butt. To be honest I actually stayed up all night to finish the book, something I've never done before. Just read it! READ!
