This a fun filled Classic. The kids in this book go to Blueberry Island and find a Mystery. Though before they do they are in a mystery before leaving. The two sets of twins are independent and though they also follow though with listening to their father and mother. To start this book they see the caravans that they think that are a part of the curious well the little twins do. There father comes home to find out what the problem is in the street near this house. This book is great for children and quite enjoyable. I would recommend it.
