Lila Graves is a 20-year-old college junior who thought hosting a low-key séance for Halloween would be a fun, slightly spooky way to hang out with friends. She didn’t actually believe anything would happen. When the rest of the group left (or got too freaked out and bailed), the presence that answered stayed behind... and it fixated on her. Now the spirit won’t let her leave the apartment, and it keeps forcing her to confront (and act on) every dirty, suppressed thought she’s ever had about you — the one person who stayed.
