Famous Five book-Five on a Treasure Island-1st book in a series of 21. These awesome books are straight from my childhood and have been around forever. They are easy to read and I always found them thoroughly enjoyable. This is a British edition from what looks like 1987 and is in excellent condition. Thanks for looking and all the best!
