Izzie and Ozzie, Grandad Paul and Nanny Sue are out for a drive when they come across a caravan event at a local Garden Centre. One rather fine but old caravan takes their eye. The owner, who only wants to part with it to the right people, gives it to them as a gift, as he can see just how Juniper--the name of the caravan--would fit in, especially with two young children who could have adventure after adventure with Juniper and all the wonder and magic that hides within her. But will Ozzie believe as much as Izzie?
