Reads like a serialized novel that was made up as it went along without a strong plot. The author introduces and tries to develop a couple of ideas (toti-potent individuals and enhancing females with an Equalizer drug to make them "equal to a man"), but neither of these ideas, nor anything else in this novel, is developed into a coherent whole. Not a good effort from a Grand Master of Science Fiction. ( )

Readable, but making little sense at all. The cover mentions Aliens, but there are no identifiable aliens. The plot stumbles along messily, jumping time and location frequently with plot holes the size of Canada slumbering towards an unsatisfactory ending.

On the plus side, its short. ( )

Despite it's abrupt and unconvincing conclusion, this story functions much better as a standalone novella, than as the major component in the The Moonbeast- the worst fixup novel of VanVogt's that I have read.
There's a nice edge of paranoia to the novella. In my mind's eye, I can almost see Phil Dick, his pupils dilating, as he read Van Vogt works like this. ( )
