Trickery Treat

In this novel it's Halloween, and Piper is busy decorating the Manor, which has become the neighborhood hot spot on the most bewitching night of the year. Meanwhile, Paige decides to use the party as a chance to honor the dead. She casts a spell that creates a portal for a clan of leprechauns...and other wandering spirits. The guests are thrilled and impressed with the realistic effects, but Phoebe, Piper, and Paige soon realize that they have a big trick to deal with: one not-so-friendly ghost going out of his way to turn the Manor into a haunted house. The Charmed Ones must stop this evil soul with a vengeance before he takes the life of one experienced ghost hunter who knows his story and has met him before.

The recurring theme in the novel is Ghosts; like in the series their features are highly distinguishable.

Ghosts are spirits that have not moved on to the otherworld yet. They are stuck because they have unresolved issues, are kept by malevolent entities or due to spiritual confusion e.g. when souls die a violent death together. When souls die at once, the good ones can't move on because the bad ones are holding them back and vice versa.

Usually ghosts are stuck in the place they are haunting however at All Hallow's Eve they can move freely.

Ghosts are stuck in their own reality trying to force everything to fit it.

Ghosts can not be frozen.

Some evil spirits need a dead body to transport them across water.

Ectoplasm is the ghosts skin, It's outside the visual spectrum.

Evil ghosts use plasma balls as weapons. Plasma balls are similar to energy balls but are materialized on the spiritual plane.

There are three ways known to vanquish evil ghosts:
 * 1. Spread a potion over the bones
 * 2. Destroy the object of the curse
 * 3. Cast a spell on the astral plane

Potions/Rituals
Sea salt that has been blessed under a full moon can diminish ghostly energy.

Rice compells playful spirits to count every grain and distracts them.
