Age: 7th-10th grade

Plot:

While the protagonist is 14-years-old, I feel like this was a much more advanced reading level than, say Harry Potter. I honestly think the book was poorly written in terms of jumping/ignoring vast time periods (oftentimes within a chapter which may cause confusion for a younger reader), confusion of what grade level the protagonist is in, over-saturation of computer/mathematics terminology, and lack of describing a character's motivation behind his actions. I read about 100 pages of this book and could not get into it (it's total is around 600 pages).
