Under the hill and far away is the land of the Fae -- world of magic and mystery.

But what happens when a pair of curious Sidhe twins from beyond the hill decides to visit a human market faire and lose their hearts.

Aisling and Ailill venture into a human village on the day of Market Faire and find their lives changed forever. Sensitive and shy, Aisling fears the mortals she walks among, and brash Ailill lets his curiosity get the better of him.

After a quarrel, the two part, and each finds themselves drawn to one of the humans they meet. From there, the story follows parallel paths as Aisling goes to beg the queen of the Dark Sidhe to remove her wings and make her human for the sake of Fergal O'Connor, and Ailill works to persuade the Dagda, King of the Fair Folk, to make his love immortal. Danger lurks at each turn of the path, and the world is full of wondrous being, both fair and foul.

Can true love triumph and find happiness when Sidhe Moved Through the Faire?
