This book is laid-out very well and quickly draws you in. You must be patient when reading the book. Many points that are made throughout come together later. Evidence (some perhaps coincidental) mounts as you are taken from continent-to- continent, and you are also versed in map-making and astronomy. You can't help but to take notice. I almost gave this book a 4 (instead of a 5) due to its shear size, but you just have to stay with it. Have fun!
