An amazing read through and through, a nightmare that has you confused (and I suspect Dick was confused writing it too), set in a world that you you learn about from peripheral information, one of Dick's more subtle works for sure, and a very good read. The only problem is "Part 4". The Epilogue. Honestly, to anybody considering buying this book, I would honestly suggest just not reading it. I know it is tempting, but it takes away a lot of the punch that the book offers.
