if I was younger I would have enjoyed this more. there is a lack of depth in the characters for me and the plot was a bit slow. the riddles and puzzles were a little too easy. I am not usually a fan of so much happening in a short time. I think this whole book happens in like 2 weeks. right from the beginning I knew where the ending was pointing. but a very easy and fast read, super short chapters. not sure if I will read the rest of the series yet.
