After some googling, I found the review.
The title of the book was "A Kind and Just Parent: The Children of Juvenile Court"
Obama’s review of Ayers’ book says, “A searing and timely account of the juvenile court system, and the courageous individuals who rescue hope from despair.”
Now, I hope no moderators are paying attention, because this post contains two separate violations of forum rules. First, it's way off topic, because it has nothing to do with Joe the Plumber.
Not only that, it also violates rule 4. That's the one about posting copyrighted material in its entirety. You see, the one sentence quoted above from Obama's review of Ayers' book is not an excerpt. It's the entire review. I would try and find an appropriate excerpt, but I think such a glowing review would have its import diminished if even a single word were removed. I therefore throw myself upon the mercy of the court.
