Addendum: This was one of my earliest posts and I was trying hard to be very positive in everything I wrote at that time. I still think it's important to be positive (as opposed to pointlessly negative and picky), but there were always a few additional things that bothered me about this post and this book. In rolling past it again today, I just had to add them in.
First and foremost, I would emphasize that the best part of this book to me is still that it starts so strongly with Karl and Coretta as key characters and especially their interaction. I enjoyed that, even when it consisted of avoidance rather than actual contact. BUT 1) the over-the-top villains -- although well-described -- were pretty hard to take seriously. And 2) when I said "compelling to the end," I was conveniently ignoring the epilogue. That section was mysteriously pat and didactic and delivered by ... whom? Not the character I was expecting to hear from, and it felt awkward. That's it. I'm done now.
