'It's time for the Great Mystery Party, where Astara, the newest Fairy Queen, will learn about the great mystery of Faraway Island.
'The two previous queens, the Moon Fairy and the Midnight Fairy, meet with her to instruct her. They tell her that every hundred years the Queen must go on a journey and attempt to join the sceptre and crown with the diamond heart of Faraway Island. By doing so, the Queen's powers will be strengthened and she will become the keeper of their fairy powers.
'Should Astara fail in her journey, the fairies will lose their magic and vanish. Astara is horrified to learn this mystery, but reluctantly accepts her mission.
'However, early on in her journey, her crown and sceptre are stolen by Lord Foulweather, King of the Goblins, rendering all the fairies powerless.
'Meanwhile, Lord Foulweather is using fairy magic to cause all sorts of problems, such as creating a drought in the land so he can charge everyone for a drink. The fairies must join forces to recover the sceptre and crown and put a stop to Lord Foulweather. ' (Publication summary)
