The Door On The Thirteenth Floor

Daniel Marlowe had never intended a town to grow around his unique mansion, but it did. The mansion was a representation of Pandora's Box (the room at the very top), the cross between Olympus and the Elysian Fields on twelve floors, and Tartarus below. It was intended to be a paradise for his bride-to-be. Together, they would rule the manse as both Zeus and Hera and Hades and Persephone. In that room on the thirteenth floor, he placed a demon to protect the manse from all who would do its inhabitants harm.
A demon to protect paradise from its own kind. A demon composed of all that was evil within himsef. But happiness was not meant to be and one person's evil set into motion the fate of both manse and town...and all who come into the presence of both.  The Door On The Thirteenth Floor is a tale twenty years in the making and covers over 100 years.
