The village of Wootton Major is well-known around the countryside for its annual festivals, which are particularly famous for their culinary delights. The biggest festival of them all is the Feast of Good Children. This festival is celebrated only once every twenty-four years, and the celebrations take the form of a party to which twenty-four children of the village are invited. The highpoint of the party is the Great Cake, which is remarkable for its hidden magical ingredients. Whoever swallows one of these is given the rare gift of an entry into the Land of Faery.

This year the magic star hidden inside the Great Cake was eaten by a blacksmith's son. The boy did not feel any of its magical properties at once but on the morning of his tenth birthday the star fixed itself on his forehead and marked him as one intimate with the Faeryfolk. This boy grew up to be a blacksmith like his father, but in his free time he roamed into the Land of Faery. The star on his forehead protected him from the evils threatening mortals in that land, and the Folk called him Starbrow and told him about their land and its hidden beauties and dangers.

The years passed and it was now time for another Feast of Good Children. Smith had had his precious gift for most of his life now and the time had come for it to be passed on to some other child. So he gave up the star, and the mysterious new Master Cook baked it into the festive cake once more.

Funny, frightening and always fascinating, the book is in part dominated by the character of the earlier Master Cook, a shallow, sly and lazy man called Nokes. He is the foremost among the non-believers, and dismisses all things magical as mere dreams and fancies. In the end it is he who meets the King of Faery and who is told off by him for his greed and indolence.
