"The Shallows"

by John Langan
originally published Cthulhu's Reign, 2010

A day in the life of a man living after the return of the Great Old Ones.

Not much of a synopsis and not much to say here, because, though very well-written, the story doesn't make much of an impression.  It echoes a bit with I Am Legend and Stephen King's "The Mist", but there's nothing terribly exciting going on here.
