Reading this book as a Christian, I found that this book started quite generically. But towards the end, as it focused on the theological virtues of faith, hope, and love, it found more of its feet.
Initially it was a broad description of morality in modern society, and it broadly makes a case for the fact that morality should play a part in 21st century society. If that's what you want, then fine. As a Christian reading this as a Christian book, I felt that it didn't engage with what 'the good life' means from the perspective of Christ. Until the end, there was nothing specifically Christian about it, other than Christian sources being slightly preferenced for quotes.
