The Treasures of Carmelidrium — N.R. Williams

While on her way home for spring break, Missie swerves to avoid hitting a man in the road and ends up in the medieval world of Gil-Lael. Prince Healden is drawn to Missie by a powerful force when she plays her flute. He knows she's the fulfillment of prophecy, and must be protected, all the while his heart falls in love with her. But, lurking in the shadows, is an evil sorcerer, Renwyk, Lord of the Symberveen, whose lust for power threatens to destroy Gil-Lael, Healden and possess Missie for his own.
