After finishing this book, I felt like I had read a solid YA almost scifi book from a talented author. The plot was well structured and the writing was very good. I did not feel overly passionate about the book, but sometimes that just happens. Though not a requirement, I think it would be helpful to read this book as a soccer fan. I have never really been into soccer, so I think that fact dampened my experience of this book.
I had only a few problems with the book, and they were minor. I did feel like the dialogue was a little off. Though teenagers should and do talk in a different manner than adults, for some reason these teenagers seemed too trendy. Maybe it was my adult brain reading cliche teen phrases and being annoyed by their very existence in the world, but I did not enjoy that aspect of the characters.
Also, I'm not a science buff. The author did a wonderful job of explaining the concepts in an interesting and understandable way, but I personally don't really get into science. If Eric had a knack for writing or reading I would have been all in. :)
This is a cute easy read with lots of fun and intriguing plot twists.
