Or novella, at any rate, is available on amazon.com. Please note that this is the PAPERBACK version. The kindle version should be out sometime tomorrow.
From the back cover:
A single room in a hospital now closed and condemned. A single room where more patients died than any other room within the hospital walls. A single room with more rumors and stories of darkness and evil than anywhere else in the building. A single room where shadows live - and they are hungry. A single room that might well claim one more life before the hospital is destroyed for all time.
