Meet the Flying Doctors: Princess Pearl, Sir Gadabout and, of course, their trusty ‘air ambulance’, Zog the dragon, in this fabulously original sequel to the best-selling Zog. They soar over the countryside, tending to sunburnt mermaids, sneezy lions and distressed unicorns. But when the king himself falls ill, can even the Flying Doctors save him?
