When the new librarian knows your name before you introduce yourself, most students don't think twice. Jordan Hayes does.
Thornhill School looks like any other school, classes, homework, sports, drama. But Jordan quickly learns that some things don't add up. Mrs. Finch, the school librarian, greets every student by name, even ones who've never set foot in the library. She's been working at Thornhill for decades, yet somehow never ages. And the library is always cold, no matter the season.
When Jordan teams up with observant Alex Carter and skeptical Maya Lewis, they uncover an impossible truth: Mrs. Finch has been dead since 1956. She's a ghost, bound to the library she died protecting, sustained by something she takes from students, fragments of their fading memories.
Small things. A forgotten teacher's name. A childhood friend's face. Moments that were already slipping away.
But Mrs. Finch doesn't destroy these memories. She preserves them, writing names in book margins, keeping careful records in the sealed archives upstairs. She's been doing this for seventy years, maintaining her eternal vigil over memories everyone else has abandoned.
Now the school plans to demolish those archives. If they succeed, Mrs. Finch will fade forever, and seventy years of preserved memories will vanish with her.
Jordan, Alex, and Maya face an impossible choice: expose the truth and risk everything, or find a way to protect a ghost who's been quietly stealing from students. As they dig deeper, they discover that some secrets are worth keeping, some mysteries don't need solving, they just need understanding.
And sometimes, the most important thing you can do is see someone who everyone else has overlooked.
Perfect for readers who are ready for a mystery where the monster isn't the villain, and saving her might be the only way to preserve what truly matters.
The Librarian Who Knew Everyone's Name is the fourth standalone adventure in the Thornhill School Mysteries series, where every book delivers one mystery, one monster, and one secret that must be kept.
