It is written in an elegant, eloquent prose, and the basis of the book alone struck me as a stroke of genius.
I mean here is this character, "The Wicked Witch", that the entire free world knows, and has known. And yet what do we really know about her? How did she become 'wicked'? Was she born that way? Did she turn 'wicked'? What makes/made her 'wicked'.
What we get is a novel filled with complex political maneuverings that follows the entire life (and death) of a woman who herself is contemplating the nature of evil.
Loved it.
