The science fiction horror story, Human Brain Soup, is worthy of the genre, it is the most shocking that I have read.  This futuristic story, operating on many levels, powerfully illustrates the horrors that farm animals endure by rudely shoving humans in their place. 

Human Brain Soup tells of the planet Huw, on which super intelligent, ant-like Huwites with 200-pound brains raise humans in automated meat factories as farm animals for their delicious brains.  Baby human brain and old human brain are delicacies.  Humans live a hellish life on Huw as farm animals and as worker slaves.  

Meanwhile there is trouble on Earth, where the United States, no longer the only superpower, retaliates capriciously against suspected terrorist targets.  Traditional US allies form alliances with former enemies to stand against the new US threat.   

Then one day, the two worlds collide when aliens from the planet Huw visit Earth. They have been sent by the Huwites on a scientific mission.  The Master Huwites are in complete control.  As they say on Huw, 'There is no match for having more brain!'  Or are they?  For one thing, the Master Huwites cannot control the Huwite terrorists that are struggling against the cruelty and injustices that are central to Huwite society.
