Bests & Worsts Reviews from Amazon

I have been looking for historical fiction like that written by Victoria Holt and Dorothy Eden. They managed to write good stories/mysteries/romances without all the graphic sex. I thought I had found one in Ambersley. I loved the story line, the characters, EVERYTHING and would have given it a five star if it hadn't had pages of graphic sex. There was no warning in the reviews, so I am writing one. I would have loved to share this book with my daughters and friends but couldn't because it would betray the kind of trash I read, even inadvertently. I wouldn't want to contaminate their minds, either. How can I find books without all this stuff?
