What this book is about

Jules Larsen, recently unemployed and evicted, takes a mysterious apartment-sitting job at the Bartholomew—a Gothic luxury building on Central Park West. The rules are strict: no guests, no leaving at night, no fraternizing with residents. When other sitters start vanishing, Jules begins to suspect the building's glamorous facade hides something monstrous. Sager's gothic thriller pays homage to Rosemary's Baby while building its own atmospheric dread.
