Mostly I agree with R. Stephan (previous review), however I think the final explanation is scientifically sound and quite original. Worth reading.
Because I grant "concession" to early sci-fi writers I expect a lot more from modern ones. The storyline is vague with an Aesop/Luddite type thread within it. Nothing special but I won't tell you not to read it.
Good portrayal of a lustful, lazy 17 year old spoilt male brat. I would have ended it differently as you might see. Worth a look.
