Anagril's father suddenly dies and she moves from London to her families Fairy Cottage to start a new life, but why does she feel someone is watching her? She loves Daniel and finally agrees to marry him. They become friends with two strange cousins. Anagril feels attracted to Paul but refuses to give in to the strong attraction, while the other, Owen, becomes her confident. But she is betrayed, for the cousins are working to a plan which almost drives Anagril to madness.
Below the hill, hidden away for centuries, is a fairy city and the fairies want Anagril, she is crucial to their long term plan. Their powerful wizards must make her give up her world and descend into the darkness and become a Fairy Queen. Anagril fights their possession but finally she must make a choice and the only one she can make and keep her sanity is to choose the dark. But the darkness holds worse than the cruel fairies and Anagril, still partly human, must make hard choices as the world of her mother beckons and finally engulfs her.
She must leave her old life and live in the darkness beneath the Earth until the time, long awaited, when the Fairies will reclaim the surface and man will fade.
