A chilling supernatural mystery featuring one of literature's earliest female occult detectives.
On the misty Sussex Downs lies Old Dannow Manor, home to the Hammand family—and a terror stalking their bloodline for a thousand years. When the "undying monster" awakens after forty years, attacking Oliver Hammand and leaving murder in its wake, his sister Swanhild refuses to surrender to fear.
Enter Luna Bartendale—"supersensitive," investigator of the paranormal, a woman combining "the functions of the White Witch and detective." Luna believes the horror lurking in the pine woods exists in a Fifth Dimension—the hidden realm of monsters born from the human mind.
As Luna guides the Hammands through ancient archives and the secrets of the Monstrous Man carved into the Downs, she unravels a curse older than England itself. Confronting this undying evil will test her psychic gifts against a terror transcending death.
