An unusual book with special interest in the intense approach to nature. In the middle of dense forest, bordering a lake, Peter followed by his more timid brother Jack, embark on a crude, handmade raft and row out to a fantastic floating island inhabited by thousands of blue-white birds. On makeshift skiis, they explore the island, literally sinking into adventure every step of the way. Real terror is achieved in the night on the island, until an accident of tide brings them to shore again. Henry Pitz' black and white sketches have caught the tense quality of the story. Not a book for sissies, but red-blooded youngsters will love it.
