While this book introduces a few interesting concepts (at least to me) such as information assymetry, and the first couple of chapters are really engaging, the rest of the book (50%) is really weak. The chapters about what makes a good parent don't really fall through, the second one is full of tables of baby names, and then it only goes downhill, including some sort of random author bio where he's called genius a good handful of times, raw articles from press and a Q&A (?) with the authors.
