The author of the fabulous "Ubik" has left many small beads that should be discovered. This collection of stories is very entertaining. The deeper, "the frozen journey" is really well done and you end up without difficulty in the head of this poor traveler awakened too early and have to wait 10 years alone aboard his shuttle to your destination! I love the style of Dick and I think this little book is very well to address this author. "Ubik" is more psychedelic and can be more difficult to access for a first encounter with this monster of SF!
At least for a good time this "frozen Voyage" is quite recommended!
