Input: I've not read this book, but some friends said it was very good. However, I don't know where they got their information. When my friend and sister called back, after I bought the book she said, "Oh wow, so that's how it's done.". I'm just saying that because people shouldn't waste their money. It's all hearsaid. My friend, who is an accomplished author, also said her editor asked her to tone down the profanity in order for it be passed as a Christian book...
Output:
Bad review
