Alexandra Watts suffers from a mundane existence. She gave up the pleasures of an aristocratic life for the rush of owning a book shop, but something went awry, and she cannot recall what. Now she wanders the musty aisles of her employers library, bored and feeling lost.
When she discovers a mysterious lady loitering the library with a book she has never read, Watts feels immediately intrigued and strangely awakened. Three things follow in quick succession. Watts is followed by a monster, the mysterious lady appears outside of her apartment, and the window to her flat is left open.
Subsequently, Watts is pulled into a mirage of monsters and Gatekeepers, memories filled with ghostly shadows, and a grove on the edge of England.
