Have yourself a very Merry Witchmas in Holiday Haven, where the magic and mystery of Christmas is snow joke!

After five years of running the Holiday Haven Inn, Carolyn Highcrest thinks she can handle anything. She and her best friend Mercy are determined to make their festive weekend celebrations the best they can possibly be, despite being surrounded by scheming rivals, melodramatic theatre group members and overenthusiastic carollers.

What Carol didn't anticipate was a visit from her eccentric family, whose knack for trouble and attachment to their cringeworthy custom-made hats threaten to derail her focus. To make things worse, a magical wishing box intended for the weekend's event disappears, and soon after, a string of inexplicable pranks hits the inn, seemingly a result of the box's powerful magic.

Carol is inclined to blame both the theft and the pranks on her long-term business rival, Janice, but all too soon, events are spiraling out of control. Can Carol fix the trouble before the holiday cheer is ruined?
