This is the third book in the Robert Langdon series by Dan Brown. I had read The DaVinci Code first and then followed it up with the first book, Angels and Demons. Angels and Demons was a slower book than DaVinci Code but not too much. It's been awhile but The Lost Symbol seemed almost as fast paced as The DaVinci Code. It only took about 2 days to read.
This book is set in Washington DC and incorporates the legends and symbols of the Masons and how the founders of the country fit into the Masonic history. It also covers some pretty groovy science, Noetic Science.
As always, Dan Brown did a great job combining ancient myth, legend and mysticism with modern reality and science.
From what I can tell, the provable science of Noetics in the book is a bit further along than reality. Although, my research regarding Noetics has been pretty cursory at this point.
I really enjoyed this book. It was fast paced but kept my brain moving with a variety of story lines going at once as well as hitting on ancient beliefs of many kinds and modern science and "reality." I recommend this to anyone looking for a quick, easy and fun read.
