"That Of Which We Speak When We Speak of the Unspeakable"

by Nick Mamatas
originally published in Lovecraft Unbound, 2009

A group of teens have gathered in a cave to drink beer and get high.  Shoggoths have appeared in the world.  Attempts to destroy them have all failed.  One of them, Jase has visions of the end of the world which may or may not be accurate.  A shoggoth kills him.  It appears it will kill the others.

Another effective but ultimately minor tale.
