Hmmm, good question. I'd say the character of Zenia in the Robber Bride brings an element of myth (she's a witch, a monster, etc.) but beyond that I'm not too sure.

I love re-reading The Robber Bride by Margaret Atwood. As I age I find that life experience gives me a deeper view of the characters and their relationships. Pretty much any book by Carol Shields or Margaret Laurence also has this effect if I re-read them.
