[EX Q]: It started with a great plot...until he actually wrote it. It was overwritten (it takes pages before something happens) and the protagonists were hard to like. Boring, sappy novel written as if he trying to imitate Victorian prose. There are a couple twists, but the main characters are such morons, it underscores the little action that does happen.
[EX A]: Negative

[EX Q]: I had seen this authors' works offered for free on the Kindle page and since the price was right downloaded two of them. I was happily reading "The Lamp In The Desert" when I got to location 2458-61, and there in the middle of the page was the "N" word. Now I realize these books were written in a different time, and people had different morals and people were unenlightened, my problem now is, do I want to read a book written by someone so obviously contemptuous of me, no matter what decade the writer lived and worked in? I think the answer is NO! I was truly enjoying the book up until location 2458-61, and had even gone so far as to call my sister and recommend them to her. I am truly trying to be a bigger person and but I cannot truly support people who do not respect me. I am deleting this book and the "Rosa Mundi and Other Stories" today. Life is hard enough and I shouldn't have to fell insulted by something I bring into my home for pleasure. Sorry Ethel, ya gotta go!
[EX A]: Negative

[EX Q]: The proof of a book on health issues is in the results it gets you, and it's very hard to argue with the results I've gotten from following Dr. Bernstein's plan. Many others have reviewed this book more capably than I can, but let me just say that after a few months of following Dr. B's diet, I've lost 50 lbs., gotten normal blood sugars, and feel better than I've felt in years. Highly recommended!
[EX A]:
Positive
