House on the Borderland - William Hope Hodgson - Bog

The House on the Borderland
Have you ever wondered what a place would be like where you were outside of time and space, neither dead nor alive? Where you could observe the mechanisms of the universe and see the death of our planet and sun? Where you could commune with souls of the dead in the black, silent sea of sleep?

A manuscript is found: filled with small, precise writing and smelling of pit-water, it tells the story of an old recluse and his strange home - and it's even stranger, jade-green double, seen by the recluse on an otherworldly plain where gigantic gods and monsters roam.

Soon his more earthly home is no less terrible than his bizarre vision, as swine-like creatures boil from a cavern beneath the ground and besiege it. But a still greater horror will face the recluse - more inexorable, merciless and awful than any creature that can be fought or killed.
