The story begins in the magical Kingdom of Melloria. King Godfrey and Queen Letitia have been having a blistering argument about the king staying out very late (like many married couples), but are trying to stay polite because they have a visitor at their palace.

The visitor says his name is Harry Potter and he wants to buy a book from their royal library to help him and his 2 friends find a set of caves where a group of unusual people live called the Korals. These caves, the Caves of Desire, are in a very remote part of the kingdom and only one book can guide the 3 travelers (Harry, Ron & Hermione).

The Korals love to sing and play amazing music and also love to practice other arts of pleasure like cooking fabulous food and...love making. To reach them involves passing through dark places where werewolves, vampires and other strange beings lurk.

Harry desperately wants the book, but he has to persuade King Godfrey and especially Queen Letitia to part with the book and overcome the Queen's suspicions that he is not who he says he is...
