The BBC Radio production of The Voyage of the Dawn Treader is a delightful two-hour sail on the most fabulous ship in Narnia. Lucy and Edmund, with their dreadful cousin Eustace, get magically pulled into a painting of a ship at sea. That ship is the Dawn Treader, and on board is Caspian, King of Narnia. He and his companions, including Reepicheep, the valiant warrior mouse, are searching for seven lost lords of Narnia, and their voyage will take them to the edge of the world. Their adventures include being captured by slave traders, a much-too-close encounter with a dragon, and visits to many enchanted islands, including the place where dreams come true. The adaptation is faithful to its source, C.S. Lewis"s series of Narnia books, which have provided exciting and uplifting tales for generations of children. BBC Radio does wonders with sound effects--the ship creaks in the wind, the sorrowful dragon roars lugubriously--and musical cues and interludes that keep the pacing dynamic. There"s also a splendid cast of plummy British voices, making this far more than a book read onto cassette--it"s an audio drama, as enjoyable as a trip to the theater. Grownups who buy this tape for their children will want to borrow it for themselves. (Running time: two hours, two cassettes) --Blaise Selby
