I think it's definitely worth reading this book (take some time and read it over several days - there's a lot of content here to absorb and consider). It covers the topic of 'human development' from early infancy through old age and even death. It considers such topics as genetics, language, self regulation, cognitive development, and more. It's well researched and very clearly presented (a model to emulate, really). Having said that, readers should take the advice in the introduction to heart: follow not only the overt curriculum where you learn everything, but also the hidden curriculum, where you question everything. "Assumptions, of which we are often unaware or which are intentionally hidden from us, nevertheless have a profound impact on developmental research and on the contexts."
