Joan Lowery Nixon is the author of "Nightmare." Most of her 130+ books are mysteries, including "Nightmare." She even said, "writing mysteries was even more fun than reading them. From what I read, she is extremely good at writing mysteries, and has gotten tons of awards for them. The Emily, the main character of "Nightmare," likes to be alone, just like Joan when she is writing her novels. The author's life lets me understand the weird plot of the book because Joan is very weird and likes to make her book similar to her experiences.
