Alice-Miranda Highton-Smith-Kennington-Jones has survived her first semester at boarding school. Now she's headed home for break - and she's invited Jacinta Headlington-Bear, the school's second-best tantrum thrower, to join her. The two girls are looking forward to a fun mini-vacation. Nothing too eventful! But a cranky boy is causing mischief, a movie star has come to visit, and a stranger is snooping around. Add a naughty pony, a hint of romance, and a dastardly scheme, and Jacinta and Alice-Miranda might have a more exciting time than they ever expected. . . .
