Oz is a ten year old boy living with his mom in a big haunted house. His father died two years ago and the family is still trying to get over it. Oz, along with his two best friends, hear footsteps in the house and they proceed to try and solve the mystery. But they stumble upon something big that they can't handle. Does the obsidian pebble he finds in his dad's study addressed to him, have something to do with the mystery, or even his father's death?
