This was my bus book for the past month or so (i.e. the book I pull out on public transportation) and, while I'm not entirely sure it was meant to be read in 40 minute chunks, I certainly enjoyed it.
Davidson is brilliant at being inviting, engaging and inspiring--the stories and research she weaves together throughout this book make me want to leap up and change the world. Without ever falling into the realm of obscurity, she tackles complex concepts and, most important to my mind, provides solutions.
Davidson presents a compelling view of how the world needs to change and, through clean prose and clear enthusiasm, invites her readers to help. If you're interested in psychology, education or just knowing a bit more about the world we're living in, I highly recommend picking up this book.
