Quick one.
What is the title of the book about the stratification of society where one group of privileged humans live on the surface of the earth and are occasionally eaten by the grunts banished to the underground.
thanks!
HG Wells, “The Time Machine” certainly fits that criteria, with the Eloi and Morlocks.
That’s the one! For some reason I thought they were called ‘Elan’. No wonder I couldn’t google it properly. 
And it’s available for free from Project Gutenberg: The Time Machine by H. G. Wells | Project Gutenberg
I thought you were referring to ‘The OC’. :eek:
My bad.
Just saw this. Thanks for the link.
