"Chester lives with his Grandma, his cat Mr. Pickles and Simon the ghost. Lately Chester has been feeling like he's missing out when he sees other families out doing fun family things. So when Chester gets the opportunity to join his friend Amie and her family on a trip to the water park, he is IN. Meanwhile, Simon is off to his yearly ghost conference, excited to finally have something to show off about (haunting his VERY OWN HOUSE, for example) to the cool ghosts. Maybe they'll even accept him into their group! Will things go as planned?"-- Provided by publisher.
