Luneta is tired of living in dull Orkney with her mother and father (the most boring knight of King Arthur's Round Table).

She prides herself on always getting what she wants, so when the opportunity presents itself, she jumps at the chance to stay at a family friend's castle near Camelot.

Her handsome cousin, Sir Ywain - a young knight seeking adventure - arrives just in time to escort her.

Along the way, they pick up a witty, honorable knight-turned-fool named Rhience.

Before their journeys end, they will face danger, enchantment, trials and sorrow, all for the sake of love and honour.
