Many authors make the attempt, no more than a handful succeed.
When the attempt is less than successful, the book stands a great chance of being boring. Too many times when an author reduces, eliminates, or re-channels internal conflict, sexual tension disappears. Obviously, a romance novel cannot succeed without sexual tension. Great story-telling, strong characters, often a mystery to be solved, and, generally, a great deal of wit and humor. One author who succeeds quite often in this arena is Andrea Kane.
