The Soul Thief

After her only living relative is unexpectedly killed in a car accident, Alyce Hampton inherits more than a luxurious estate. On a shelf in the manor's study rests a collection of ominous crystal globes. Amidst the swirling, opaque mist of each globe appears to be a person, trapped inside. Alyce soon learns the globes contain souls that have been stolen over hundreds of years by a demon named Orson.
Orson invades the living host and forcibly evicts the soul, which is imprisoned in a crystal sphere as a trophy of Orson's mastery over life itself. He moves from person to person, enjoying the advantages of the mortal existence he was denied. Now, angry at having lost possession of his globes, Orson will do anything to get them back. With her life in danger and time running out, Alyce is in desperate need of help.
But how does one fight a demon?
