To be honest, I didn’t really enjoy reading this book very much. The idea seems interesting, but I think, it’s too “stretched”☺ In my opinion, this story would’ve been far more interesting to read if it had been shorter. The idea of using marbles as the key thing in a story is very unusual but the book itself wasn’t very gripping. And, honestly, I was expecting a more unexpected ending like that Fergus would remember everything.
I give this book 3/5
