I received the product in a timely manner. It was as advertised. I have used it a number of times and it works well although I haven't gotten the results from it I had hoped for. No fault of the seller or the product though.

Even that single star is more than this book is worth. My Engligh professor assigned this book to me during my sophomore year of college (along with Nectar in a Sieve, a far better, though not terrific book), and what little I remember of it was that it was just awful (and offal). Her writing is repetitive and choppy, perhaps descriptive but disgustingly so. Do we really need to know the "wetness between [her] legs", or that she cooked her menstrual fluid into some poor soul's dinner? I couldn't stand the book. If you want quality, read something by Neil Gaiman, or Stephen King (his descriptions of a girl coming of age in Carrie are much better than this book). Drop the book, throw it, burn it, whatever. It's just not worth reading. How many trees did we lose to its production (and, more importantly, how many talented young writers were rejected because this woman was published). It's just a book not worth reading about a story not worth telling.

What a great album!!! I never knew she sang as well. I have seen her in French movies and enjoyed greatly her acting in those movies. Now I even adore her more, because not only can she act, but she can sing as well!!!Go Charlotte Go!!!! Can't wait for her next album.
