The Pit of Forgetfulness

Publisher's blurb:

Throwing open the heavy metal door, you rush through, escaping the frozen dungeons of the morgue. In your rush, you almost don’t see the huge put in front of you, and have to wave your arms to keep your balance and not fall in. Gasping, you peer down into a deep, deep pit to see the faint outline of thousands of skulls deep below the earth. Doors act as offshoots from the stairwell. Not wanting to return the way you came, it seems the only way to go . . . is down.
