Halloween is approaching which means it's time for the annual parade! Between carving pumpkins and enjoying fresh pumpkin juice, Ghoulia and her friends realize they need to find the perfect costume.

While rummaging through the attic for hats, masks, and capes, they stumble upon an old memory box. Inside are trinkets, old photographs, and a faded postcard--from Ghoulia's parents! They embarked on a voyage long ago but never returned from their trip. Where could they have possibly ended up?

It's time to put on some sleuthing gear; finding out will require detective skills and a lot of imagination! With the help of her faithful dog Tragedy, cousin Dilbert, and all her friends, Ghoulia sets on a journey to crack open the titanic mystery of her parents' whereabouts . . . before the trail gets too cold!

Ghoulia and friends return in the fifth book of this fun, full-color chapter book series, starring everyone's favorite, not-so-scary zombie.
