There’s not a whole lot of room in the classic fairy tale for moral ambiguity. Be good and good things will come to you. Happily ever after, right? Well, no. That’s not really the way life works.

The author of novels like 'The Hours' and 'By Nightfall' has taken stories like 'Beauty and the Beast,' 'Rumplestiltskin' and 'Hansel and Gretel' and injected them with a bit of hard reality.
