This book was required reading for a Molecular Biology of HIV/AIDS course and was a great launching point into the subject. The discussion on the immune system mechanisms is simple enough, yet descriptive enough, to build a good foundation on. When the class delved into greater detail about various HIV proteins the quick overview provided in the book was helpful in keeping track of everything. I would have liked to see more on societal impact and consequences of the ways that AIDS was initially discussed and investigated (this might be expanded on in later editions I don't know whether or not it has). Over all a great read.
