I really like Christine Feehan. This book was very dissapointing. The plot had promise. Nicoletta was a sweet heroine. The prose were good, and the medival Italy setting was an interesting change of pace. However, the plot flows like molasses in January. I managed to get half way through before I through the book down and went back to the 'Dark' series.

What a pleasure to read such a high-quality book... It introduces each of the islands in a colorful and vivid way. The book includes many pictures, and provides a fine insight into the culture and character of the islands and touches on history, people, travel, activities, sights, nature, and a lot more.However, if you are looking for a book with accurate travel information, e.g. hotels, restaurants, prices/dates, how to get there, etc., this book is on the weaker side. Use it together with the Frommer's Caribbean guide for a combination that is hard to beat. Despite this weakness, it's still a five star on my bookshelf.

A truly magnificent movie. Diane Lane shines in her role as Frances Mayes in this funny, sweet, enjoyable piece of great entertainment. The director makes this movie so engrossing and enjoyable that it is impossible to not be drawn into the wonderfully realized 3D characters and the brilliant played out scenes. The scenic locations help and so does the likable characters. Make no mistake... this is a magnificent movie.
