Input: Consider Input: 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.

Output: Positive


Input: Consider Input: An extremely helpful gem on a complex subject of second century religious authority and textual use. For anyone serious about this period and the interelation of cultures, this book is essential. Is it complex and detailed? Of course, it must be to argue the point. Should you buy it? Yes, unless you want to keep running back to the library. I write this only after thoroughly disagreeing with the review above.

Output: Positive


Input: Consider Input: I love all of Sophie Kinsella's books and her writing style...but this book was awful. The story line was predictable and the writing flat and unoriginal. Makes you wonder if this was truly written by Kinsella or a way for a ghost writer to get started under her 'new' pen name. I don't plan on buying anymore Madeline Wickham books--stick to the original Kinsella, where I haven't been disappointed yet.


Output: Negative
