Query: Great reference

I went traveling in Greece 2 years ago and found other travel books to lack info on the Greek Islands and had to struggle my way through the islands. As I am planning to return this summer, I have found this book to be a good reference to prepare, and one that I will bring with me. When most of us think of Greece, the Greek Isles are the place most of us invision. This book gave me a good reference as to where to go, where to stay and what there was to do. I would reccommend this book to others.
