A very good story in the Burroughs vein of stories. Good science fiction for its time.
The classic fall asleep and wake up in a different place type of tale. Unfortunately doesn't give enough explanation of why the world is that way. Not enough history of what the world was before it became that way.
Never mind the fanciful movies. This is a story of the dangers of drug abuse. I've seen similar reactions in my friends who use hard drugs. an early warning back in the 1800s.
ZZZZZZZ. A very boring book with no remarkable action either emotional or physical. It reminds me of a very boring American going through Europe movie from the 60s.
