If Will is King Arthur, his friend Lance as Lancelot, his girlfriend Jennifer as Guinevere, and Will's mean stepbrother Marco as Modred, the man who killed King Arthur, then where does that put her? She begins to believe that she is Ellen of Shalott, who kills herself for love. But with a thrilling climax, Ellie realizes that she is not Ellen, but someone much more powerful. With this power, can she save Will from Marco/Modred?
