my wife is reading it now......I write, she gets some sense of writing through osmosis and being very bright. So, she's a fair critic in her own right, somewhere between the oft-maligned "writer reviewing" and "reader reviewer".
She's mentioned, more than once, that Christian invariably has a "smile that didn't reach his eyes." I'm starting to think the poor fucker has Bell's Palsy. :-(
her final assessment was that the book started rough, smoothed out a bit, but would have still been much better if "the story was actually written well."
