Born skeptic Lilac Black does not believe in ghosts—until she is thrust into the secret world of seers and spirits at the Spindlewood School.

"A perfect choice for fans of Wednesday." ―SLJ

Lilac Black knows the séances her uncle runs for a living aren’t real. So when she pretends to talk to a spirit to get him out of a tight spot, she expects a scolding, not a celebration. She certainly doesn’t expect an invitation to her uncles’ alma mater, the top-secret Spindlewood School of Seeing.

Irresistibly curious, Lilac decides to attend. But as the only Unseeing student at a boarding school full of Seers, she has to bluff her way through classes and act afraid of spirits everyone else can See. Making new friends, like the intriguing Emmanuelle, only complicates Lilac’s web of lies. And as if her big deception wasn’t enough, something is very wrong on campus.

Spirits send cryptic messages warning of danger, and every ghost on the island seems drawn to a hidden door deep in the library basement. A being is waiting down there…something none of the adults dare to talk about. Lilac and her friend Emmanuelle must use all their powers—or at least their wits and courage—to save Spindlewood from a terrifying fate.
