I re read this book after a long gap. I think I last read it back in 2006 or 2007.
This book is a typical PKD creation. It has the usual premise. A depressed and depressive employee, fatherly employer. Employee likes a girl, does something non-ethical at work, gets fired, sinks into depression and invariably into a world where he loses perception of where he is and what if anything he could have done or could do.
The best part is how masterfully PKD weaves a Web of reality vs unreality. The boundary between a drug induced dream like simulation and a real world is so blurred that the reader won't know what is real anymore.
I rate this a 7. It's not as good as Ubik or Do androids dream of electric sheep? But it's definitely one of PKD'S better works.
