Everyone in Hawkins believes Y/N died in the Upside Down. They’re wrong. Months after her disappearance, Eddie, Steve, Robin, and Billy begin seeing her everywhere. She talks to them, jokes with them, argues with them, and insists she’s perfectly alive—except no one else can see her, and every attempt to touch her ends with a hand passing straight through empty air. Y/N has no idea what’s happened to her. She remembers entering the Upside Down… and then nothing. As Hawkins grows stranger and long-buried secrets begin clawing their way back to the surface, the four of them are forced to confront an impossible truth: Raelyn isn’t a ghost. She’s a living consciousness separated from the body that’s still trapped somewhere beneath Hawkins. Now they have to find her before the thing keeping her alive finally gives out.
