Zara Riddle was looking forward to her first Halloween as a witch.

Then the little girl ghost showed up.

Zara puts costume shopping on hold, rolls up her sleeves, and does her usual witcher-i-doo.

But nothing works as planned. Mistakes are made. Dinner parties are ruined. (More than usual.)

Could this stubborn spirit be connected to a family member's past? Perhaps the Big Tragic Secret nobody talks about?

Zara won't rest until she gets to the truth, even if means pushing the whole coven to the breaking point. And break they do.

In Wisteria, when things start falling apart, there's no telling what powerful forces will be unleashed.

Especially on All Hallow's Eve.
