Cloud Atlas

An amazing book.  A mesmerizing, absorbing, memorable book.  I loved it.  Mitchell is a wonderful story teller.   He has written a masterpiece which shows the best and worst aspects of human nature are pitted against each other

Warning: spoilers!

I really enjoyed the devices he used to connect the stories.
I loved the double Matryoshka doll layering of the stories with time advancing and then peeled back.
The nested stories are beautifully crafted and sandwich together perfectly. 
I liked the subtle (and not so subtle) references to the comet shaped birth mark.
I loved the Sci Fi sections (but then I am always a sucker for a good sci fi story).
