What is the fine-grained topic of the following text: This is the beginning of an adventure which sees Jake careering across the countryside at the wheel of his father’s campervan (scenes any right-minded child will love) pursued by some very unpleasant spooks, while gathering around him a band of dead companions including a fox, and a hockey-stick-wielding, school girl poltergeist. Only return the topic.
A boy named Jake embarking on an adventure with a group of ghost companions.
