Good as always perfect package book in perfect nothing to say. The content of the book ??? So where to start, K.Dick for me is many books, sometimes complicated to follow but still a good time reading, in addition to Substance Mort, I strongly advice UBIK (obviously fans will be with me as I think ) but it is read and for those who do not want to read it remains the films "Blade Runner" for example, and many other things ...
