Wow, thank you for the effort in typing out that this synopsis! Seems like quite the compelling read.

I have already retrieved the book & will start it tonight.

I also enjoyed the TV series equally.

It's a great book. Phillip K Dick, there is no author like him.

It's a fantastic book, highly recommend to read.

There is also a TV series based on it (on Amazon Prime I think), but as usually, it's not as good as the book.
