They thought Halloween was over. They were dead wrong. It’s late Fall 1986 in Olympic Vista, and twelve-year-old Adelaide Winter is desperate for a distraction from life at home. And in this strange Pacific Northwest town, a little weirdness is never far away. The new mystery arrives as a spooky rumor: a floating jack-o'-lantern hovering over an old farm. Adelaide quickly rallies her friends for a late-night mission, only to have their plans unravel before they even step onto the property. Caught in a situation unlike anything they’ve faced, with danger lurking in every shadow, the preteen sleuths must pull together. In Olympic Vista, the tricks don't stop just because the calendar says November.
