The Possessor

From publisher blurb: Possess your friends, possess your enemies, possess your neighbor's dog You have a flexible spirit, one able to fuse with the body of another. This spiritual practice is known as “spiritual fusion” and is a form of possession that can augment the body of a friend or destroy the body of an enemy. Some see you as a leech, a parasite, or a social loaf but your capacity for good or evil is within your own hands.
