The Ghost of Halloween Past heads to Winterspell in this time-traveling tale of a bygone spooky season.

High school senior Rosella Midnight heads to the town Harvest Party hoping to score a free candy bar and avoid her overachieving cousin. But when the festival's clairvoyant asks for help, Rosella's unique magical talent becomes the key to unraveling a startling theft.

Aided by a ragtag team of animal informants, Rosella must navigate high school drama, small-town secrets, and her own self-doubts to crack the case. But when the path to the culprit leads her a little too close to home, Rosella wonders if perhaps she should have just gone trick-or-treating.

Can Rosella decipher clues from a troublesome stray cat? Or will a murder of crows prove her best ally? And most importantly, can she unmask the crystal ball thief in time to snag the last caramel apple at the festival?
