Anna and Holly Burnbright, together with their friend Prince Pepino, are trying to earn enough money to go on the intergalactic holiday of a lifetime. What they need is a holiday job. So when Mademoiselle Malypense tells them she needs help to organise the Francian Royal Wedding, they jump at the chance. But it's not long before Holly smells a rat. Isn't there something odd about a garlic-flavoured wedding cake? Could there be more to this royal couple's wedding day than meets the eye?
