Dire. The writing is along Dan Brown lines, with flowery metaphors mixed until they become meaningless. From page 1: "My father sighed, hiding behind the sad smile that followed him like a shadow all through his life." How can he be hiding behind it if it's following him? Then on the next page someone is described as having "vulturine features", but in the following sentence he has an "aquiline gaze". This sloppiness is everywhere.
The whole thing feels like it desperately wants be seen as some kind of profound parable, but the only result is that the characters are just implausible symbols. They are too bland even to hate – unlike the book itself, which I loathed.
