The first of an exciting action-packed adventure series perfect for girls and boys aged 9 to 14, it deals with friendship, loyalty and courage in the face of seemingly hopeless obstacles … It’s the beginning of the summer holidays and thirteen year-old Millie Morlock is the only student left at Dundrum Castle Boarding School. She’s already fed up and bored, but her boredom quickly changes to astonishment when she rescues a real, live fairy from the school’s walled garden. But trouble is already brewing: although Dulcie looks like the proverbial good fairy, her personality doesn’t match! The cunning fairy tricks Millie into going back to the enchanted Glens of Tir na Gleena with her, and Millie is suddenly catapulted into a world where magic is normal and anything human is barely tolerated. She’s devastated to learn that she won't ever be allowed to go back to Dundrum Castle, but when she finds out that she’ll also lose all memory of her human existence, her despair turns into determination to beat the cruel fairy laws. At first she has only herself to rely on, but gradually she attracts a group of weird and wonderful friends who are willing to risk everything to help her. Not least among her new friends is Toad, a courageous boy whose own memories of his human life are practically non-existent. Will Millie and Toad overcome their dismal fate with help from fairies Sukie, BarnabusBart and YarabeeToot? Will they finally manage to escape from Tir na Gleena? Or will they be doomed to remain there forever and slowly grow old, unable to remember their previous lives when they were carefree youngsters with no knowledge of fairy trickery and deceit?
