[Q]: I purchased this pepper grinder at a kitchen outlet store. One of the "rabbit ear" handles snapped at the base after less than 1 month of use. I don't reccomend this product.
[A]: Negative

[Q]: I was enchanted with this fascinating book on barn conversions. Barns are great relics from our past, conveying a sense of history, but many have been ruined by weather, time, and neglect. I didn't realize how many creative architects and owners have made barns useful for both residential and commercial use through renovation and restoration. The intrinsic character of these old barns brings an integrity and charm rarely seen in new construction. In many gorgeous illustrations, Rooney describes the history of barns, their adornment (who knew that it was all because of a 9th century pope that there are so many roosters on weathervanes?), and their use as gorgeous residences and fascinating commercial and establishments - including an architectural office, inns, and even a funeral chapel. One entrepreneur even used several to develop an office complex. If you love barns and if you like to see the past preserved in the present, you will love this book.
[A]: Positive

[Q]: This was an excellent book, probably my favorite of the first four. I read it when I was 11 years old, and have re-read it so many times the book is practically destroyed. However, this book, while I as a 6th grader enjoyed it, is not for the immature child. Think carefully before you tell anyone about the series, especially your child, because it contains a few explicit scenes, which increase as the books go on. Another word of advice- if you don't like a lot of details in a book, don't read this, because the author details surroundings and histories frequently. However, I thought the details were fascinating. Jean Auel is a wonderful writer, and I eagerly await the fifth book.
