When the pig called Heather woke up after lunch, the first thing she thought was that she had absolutely nothing to do. That was good, doing nothing was one of her best things, and also one of the things she did best. Heather's best friend is a girl called Isla, who lives with her dad on a farm in Scotland. Their idyllic life together is shattered when a thunderstorm destroys the farm and forces Isla's dad to sell up and move to London - leaving Isla and Heather miles apart and utterly miserable. Then fate intervenes, turning Heather from an everyday pig into a national celebrity, and catapulting her to fame, fortune and most excitingly of all ...London. Armed only with her own pig-headedness, Heather embarks on a quest to track down her best friend. After all, how many girls with freckles can there be in London?
