This is one of the better, if not the best of the Worlds of Power books. Unfortunately, that's not saying much. The problem with these books is that they are written so simplistically and poorly. Even as a kid I would have been a little insulted by the writing.

At least this Worlds of Power book didn't incorporate the unnecessary kid like the fantasy books do. That is exceptionally annoying in this series.

The writing is so bad at points that it makes one cringe. Lines like "The metal itself seemed to radiate evil," and "Time had slowed down, but each second moved too fast." I mean, eesh. Awful, just awful.

One of the best features of these books is the recommendations section in the back. They give readers the option of finding books similar to what they've just read, but written so much better. ( )

This book is actually a little bit better than you would suspect a book based on a Nintendo game would be. I know that is not saying a tremendous amount.
