This is the story of two very different sisters--Eliza, who longs to ride into battle against villains and dragons, and Lavender, who would give anything to be a pampered princess. Before the end of the story both of them have had a chance to fulfill their dreams, though not quite in the way they intended. Accompanied by their depressed goat, Gertrude, with their granny's warnings about the Black Death ringing in their ears, they head out into the forest and come face to face with an evil count who definitely does not have their best interests at heart.
