Yes, things get very hot between Claire and Jamie in the books, but in the first episode, we're introduced to Claire and Frank. While the books talk about the married couple's active sex life, in retrospect, it's a little clinical on the page compared to the show. These two have racier scenes on the show than in the first book, and much of that is due to the fact that Starz can show nudity. It's not quite Game of Thrones, but it is very steamy and sensuous.
