Shadowdance

Paralyzed since birth, a young man named Innowen happens upon a sorceress along the road. She grants him the ability to walk, but there are two conditions—he can only walk between dusk and dawn and, to keep this ability to walk, he must perform a dance in the witch's honor each night. What at first seems harmless comes with a sinister price. Anyone who witnesses Innowen's dance is soon compelled to act out his or her darkest, most horrific desires. Eased of his physical affliction only to be burdened with a moral one, Innowen sets out on a quest to find his nameless "benefactor" in order to lift the curse. What he finds instead are long-protected secrets that threaten to bring down the entire kingdom.
