I've reallyy been into short storied and enjoyed all of the ones in this book. They were all sci-fi, most based on "Terra" and various alternate universes of Earth, involving human and non-human sentient creatures. Several stories included robots and most were futuristic.
I gather from the stories that Dick must have been a smoker. Each and every single story had a character that smoked.
The book's namesake story reminds me of the movie "Total Recall"...too bad the movie (and its remake) didn't stick entirely to the original storyline.
