Halloween is supposed to be fun, right? It's Flynn family tradition to host Keyhole Lake's annual Halloween party. This year, Noelle is in charge and she's about to lose it. Between forgetting to pick up the candy and trying to work around a histrionic, living-impaired aunt, things are spiraling out of control fast.

The situation goes from bad to worse when she buys a cool crystal pendant in a thrift shop, because it isn't long before she finds out that what she really bought is TROUBLE. A restless spirit starts appearing in unlikely places and leaving cryptic messages around the house just hours before the party's set to begin. A surprising twist helps Noelle pull off what might just be the spookiest Halloween party in history.
