Heather Duroc has had some amazing adventures, but now she needs the help of her two young piglets to find their father and reunite her family . . . Heather is back on the farm in Scotland, with lots of friends, two gorgeous piglets, Eder and Tor, and all the apples she can eat. She should be happy, but there's something missing. Actually, it's someone. Or some pig. The handsome, proud, bearded pig Aitor, Heather's one true love. When an accident leaves Heather unconscious, Eder and Tor set off with Joey, a puppy who dreams of being a pig, to hunt for the only thing that will make their mother better. It's an impossible task - the piglets don't know where their father is, or even if he's still alive, but they have to try. After all, 'impossible' is a word their mother has never taught them.
