One thing I liked about this book was the fact that the copy I got was a proof book, so it had a bunch of amusing little typos in it. The sister's name was different fr a whole chapter, for example. The main character refers to his aunt's 'horse' instead of house at one point. Things like that.
The rest of the book, though? Meh. A lot of the plot hinged on people not communicating with each other and being purposefully vague. 'I guess you'll just have to figure it out on your own'. Yeah, or you could just tell me and save your pointlessly cryptic crap. 'Oh look at this interesting thing that the cop found out that I'm not going to tell you about for another three chapters.' Um, yeah, cool.
While I'm glad that the author went through and did research into Tourette's to make sure that he didn't go making a mockery of the disease on accident, the amount of information about it that made it into the book ended up being excessive and dragged the pace of the book down a lot. Considering I read almost 200 pages (198 exactly, I remember commenting on it) before we got the first whisper of plot, so much of that could have been trimmed. I'm reading a thriller here, not a research textbook.
Another thing that got old fast was the way the women in the book were described. Her perfect hair, the way the sweater clung to her perfect waist, the perfect curve of her breasts, the sweet curve of her ass, the tight line of her thigh, her perfect heartshaped face. Yes, we get it, all the women in the book, even the ones who have been declared 'too thin' or 'not his type' are perfect. PERFECT. And the cop has a raging boner for pretty much every single one he meets (except the one that's game, of course). Meanwhile, the main character? Um...he had a mustache. And...hair. I honestly can't remember anything more about him than the mustache and the fact that he wasn't a dough ball. Yet his girlfriend, and her rampant perfection on every front, is burned into my skull for life.
The twist at the end (thankfully) didn't end up being what I thought it was going to be, but it left me with a pretty severe case of 'yeah, okay then' once I got to it. All in all, the book was okay. Not one I'd read again, but okay. I guess.
