I'm surprised at the high rating other reviewers have given this book. My guess is that the other reviewers are on the young side or the author is bumping his own work.
The book is written in the present tense which is actually really distracting. It may be that the author decided to do this so that readers might associate it with the way the GM of a role playing game narrates but it doesn't make it less disconcerting.
The book's dialogue and plot are very simplistic, suitable for young readers but probably not for most adults. I found the whole book to be a demanding slog. Not recommended for advanced readers. Only barely recommended for anyone else.
