Ruby Holler is a good book. The twins are two good people that get in trouble a lot. Then they finally get to go to two old people that were really nice and they treat Dallas and Florida the way they should be treated. This book is really exciting. At first the book was sad to me because the twins kept getting in trouble. After they were sent to Tiller and Sairy they went on a trip. I would give this book a 10. I recommend this book to all ages. :)
