I know that many readers found this book mind-blowing and interesting. I really liked "Man in the High Castle" and some of his other works. "Clans of the Alphane Moon " was a real hoot. However, like many of his other novels this one left me feeling schizophrenic. I had no feelings for any of the characters and the "plot" didn't seem to make a lot of sense. It jumped from a mystery pot-boiler to an alternate reality blowout. I didn't feel that there was much (if any) resolution to the situations the characters were dealing with. I know that Mr. Dick was deeply searching for meaning and the nature of reality, and this book explores some of his angst on those issues. Some of the ideas from Eldritch carry over into "Martian Time Slip", but I feel they are better presented there. If you enjoy getting your brain spun around, then you'll probably like this book. I like reading science fiction with realistic characters and a definite plot with a resolution. The Three Stigmata of Palmer Eldritch was just not my cup of tea.
