Alice-Miranda Highton-Smith-Kennington-Jones has survived her first term at Winchesterfield-Downsfordvale. And now Jacinta Headlington-Bear, the school's second best tantrum thrower, is joining Alice-Miranda's family for term break. Who would have thought it! The two girls are looking forward to a relaxing holiday at Highton Hall. But a cranky boy is causing mischief on the estate, a movie star has come to visit and a stranger is snooping about. Add a naughty pony, a hint of romance and a dastardly scheme, and Jacinta and Alice-Miranda might have a more exciting holiday than they were expecting.
