[EX Q]: Hawthornes The Scarlet letter is an okay book. It has an okay plot and okay characters, but the book is not one for teens of the 90's. I had to read this book for my English teacher and to tell the truth if it were not graded I would not have read it. The teens of today do not want to read about the ancient customs of puritan society. If it had been about the scandalous affairs of Hester and Rev. Dimmsdale it would still be a best seller. I think this book should be only read voluntarily. If you are thinking of reading it you may need to reconsider.
[EX A]: Negative

[EX Q]: This product worked for 4-5 times and the rotation stopped working. Batteries run out or lose power after 3-4 uses. I would read reviews before buying another one... I am looking into the Hitachi wand massager now and I believe I will buy it since is a power operated toy and will never run out of power.Not impressed with this product.
[EX A]: Negative

[EX Q]: If you are interested in Renaissance Italy, gender studies, or the history of the Christian Church, this book is for you. This book presents the story of an ambitious abbess on the road to sainthood a la Catherine of Siena and her fall from grace as she becomes too powerful for the comfort of her male collegues. It is the story of the making and unmaking of a saint. This is one of my favorite books of all time.
