First let me say there wasn't anything that I didn't like about this book. It's highly readable, has great characters, moves along quickly, and I darn well spent half the night reading it!
Still, it's not going to be my favorite book of the year. I can't put my finger on it. I did not dislike it. However, I didn't love it either. Having a murdered abortion doctor as one of the main figures of the book, maybe I felt like the author was using the political issue as a catalyst? I'm not sure. She definitely tries to create sympathy for one who chooses this profession, and yet, she does a good job of not making the character entirely likable, too. So I don't even have a major complaint there.
I'd recommend this book. Particularly if you've got a long car ride, travel day, beach day and so on. It's a fast paced read and it'll keep you entertained, for sure. There's just nothing magical about the prose or totally engrossing about the storyline -- nothing that puts it in the "you have to go to the bookstore and get it right this minute" category.
