This book was such a score to read for an advanced readers copy. With more and more of the book I noticed it reminded me of the ocean series. I really enjoyed the contrasting characters and how there is a backstory between Rosalyn and Noel which makes you get even more involved with the two and their rivalry. I really like how the world in the story is constantly changing from the museum to Egypt and even some tasks along the way like on the train. When you don't know when another puzzle or competition is going to approach, BAMMM, your thrown for another joy ride. This book is nothing like I have read before and I think there's a unique place for this in the book world. I was not overly excited about the cover, but after reading the first look I am glad I gave it a shot. I really enjoyed this book and think it will be a top book for young adults who love adventures and to be on the edge of their seat!
