Rory's Piratical Leg

Rory lives with her wicked uncle and aunts until she meets a boy named Rollo, who rescues her from that situation. Together, they go mudlarking along the Thames River, where Rollo teaches her to row and makes her a wooden pirate's leg. Their treasure-hunting adventures take a dangerous turn when pirate Black Jack and his crew pursue them, forcing Rory and Rollo to use their wits to survive.
