A Castle in the Sky is the third in a trilogy of children's novels about English fairies and their mortal friends. As with Lavender Village, A Castle in the Sky puts communities of fairies and elves to the test as they strive to eradicate their enemies heralding from the Bleak Realm.

Celeste MacLeod lives with her husband, Graham, and baby, Matthew, in a renovated castle – all appears to be bliss and sunshine until the appearance of the outwardly charming weekins who wreak havoc and seem determined to drive Celeste out of her mind and regain Fellsdown Castle in Northumberland for themselves. At times, they are dangerously close to achieving their goal. What will happen to the fair Celeste? Who can overcome these seemingly indomitable creatures?

As with Lavender Village and The Mists of Afar, this work contains love, laughter and malice in equal measures. Will the Underworld conquer the Ladies of the White Way? Do indulge yourself and find out!
