Great book fascinating read a real page turner! Right up to the point where they say to get out your calculator! At that point I am lost. I am a writer and this is not my subject of expertise so it is time to pass this book along to someone who will enjoy helping X and Y find their way. Even with Dora the Explorer's help we never found out what happened to "Y."

Book is in great condition as I tried to never open it. I definitely did not write or highlight anything in the book because I would not know where to begin and Swiper Fox stole my markers.
