Igraine is twelve years old, and dreams of being a knight and protecting her parent's castle from attack like her great-grandfather, Pelleas of Pimpernel, but Igraine's parents embrace a more peaceful existence. They are magicians who have enchanted the castle so that it protects itself, leaving Igraine little opportunity to practice her chivalry. Dressed in her great-grandfather's chainmail Igraine has only her cat Sisyphus for company until the Baroness of Darkrock mysteriously disappears and her nephew, Osmund the Greedy shows up. The adventures that Igraine has dreamed of are about to come true. Can a girl become a knight?
