Through an ordinary doorway Eustace Scrubb and Jill Pole, fellow students at a miserable school, stumble upon the place they wish most to be-Narnia. The noble Lion sends the children on a mission to find the lost Prince Rilian, beloved son of Caspian, who was lured away by a beautiful and mysterious woman ten years ago and has been missing ever since. Together with Puddleglum, the gloomy but valiant Marsh-wiggle, Eustance and Jill must brave harsh terrain, menacing giants, and other grave dangers before delving into Underland to save the Prince. And although they have reached the end of their quest, their troubles have only begun.
