The angels need Lilly's help. A tragedy is going to happen Halloween night at the big party at a "legit haunted house" and unless she can stop the party from happening, a lot of people will get hurt. Lilly doesn't have a lot of time. The party is tomorrow. She can either use her social influence-which doesn't exist-or she can try to help the haunted spirit inside the house move on to the spirit world.However, to help the spirit move on, she will have to do the impossible. She will have to learn Spirit Walking.
