Very entertaining book with an interesting concept. Since the concept is built around world-hopping I did think we stayed a bit to long in the third world. I understand that the author wanted to tell that story, but I found it the least interesting of the 3 worlds we visited in this book. It was good though to learn of the “villain” back story that had visited 10 worlds to get a taste of what else was out there.
I did miss a lack of explanation to why the main driving force in the story happened. I couldn’t come up with a good logical explanation to why this whole system was set up like that. Hopefully that will come in the next book.
