The time has come for Eilonwy, Princess of the Royal House of Llyr, to become a lady, although she would much rather be seeking adventures with assistant pig-keeper Taran. Will Taran lose Eilonwy to the arms of the feeble Prince Rhun or worse still to the clutches of the evil enchantress Achren? Along with his faithful companions, Taran must negotiate the lair of the giant cat Llyan and the cavern of the King of Stones in his quest to win her back.
