I found the book completely enjoyable. Dick's writing style is colorful, imaginative, and easy to follow. I enjoyed everything about the book except for the crux upon which the plot resided, which was this mystery drug. It was handled so quick, in such a spurious fashion, and the descriptives of it left me dazed. In short, it was extremely contrived and was very disappointing. So, 5 stars for everything else, but the thing that made the rest of the story possible was just plain lame.Despite that, I do recommend this book.
