Caroline Foster arrives at the Whitechapel Full Moon Society looking for her missing brother. The building's crumbling exterior hides rooms as luxurious as any elite club. Caroline accepts a position as maid in exchange for lodging. Her employers give her three strict rules: ask no personal questions, avoid the iron-barred second floor room, and stay locked in her bedroom during each full moon from sunrise to sunset. Caroline discovers the previous maid was killed by Jack the Ripper, who terrorizes London's streets. Her brother has vanished without explanation, leaving only puzzling clues behind. Bodies connected to the Society begin appearing throughout the city. Caroline realizes her hosts conceal dangerous secrets. She suspects she has entered a world where monsters and curses exist alongside family mysteries and old magic. The Society's connection to the Ripper murders forces Caroline to confront supernatural forces she never believed possible.
