Query: Excellent, but not a Classic

The writing is easy to read, and the plot is easily understood without being too simplistic. It has sci-fi underpinnings, but does not bog the reader down with explanations that would probably wind up being nonsensical anyway. I must note, however, that the passages pertaining to the "Shadow World" video game become a bit tiresome and over-wrought. There is a twist to the end, which anyone who is paying attention can see coming, yet still manages to suprise based on the "I can't believe the author had the guts to do that" factor. In other words, its not that you didn't think of it yourself, its that you didn't think anyone would actually DO that - which adds to the fun of the book. I could easily see this book being adapted to film.
