This is a tremendous book and a refreshing alternative to more canonical texts on stellar physics that are abysmally poorly written. I read this book on my own to help me study for my stellar physics class and it served me well. The book is clear and thorough in its explanations, down-to-earth and non-stilted in its tone, and has excellent summaries at the end of each chapter. It is also very well-organized and replete with worked examples. As a reference for an undergraduate-level class, this is truly a gem. The only reason I give it 4 stars rather than 5 is that I wish it went more in-depth on radiative diffusion and convection. In particular, it does not provide a derivation of the radiative diffusion equation, and it doesn't include anything about mixing length theory, convective velocity, etc.
