The Moonspinners

It was a fun read, and refreshingly, the movie was quite different, so the suspense and plot was fresh. I'd say the movie was generally more enjoyable, but I did like how this Nicola had much more agency and was far pluckier than Hayley Mills' Nikki, if not quite as charming. I did much prefer the book Mark though. Less of a jerk.

Still, if you had to pick one, I'd go with the movie.
