# Castle of Mystery by Mary Pope Osborne (Paperback)

Eight-year-old Jack and his little sister, Annie, are playing in the woods during their summer holiday, when they find a mysterious tree house full of books. But these are no ordinary books . . . And this is no ordinary tree house . . .

Jack and Annie find themselves on another adventure - this time they're in medieval England. It's exactly the same as the story book - there's a castle and a banquet and knights on horseback. But when they find themselves locked in a dungeon, Jack starts to wonder if they'll ever get home again . . .
