I read this book thinking that it ws going to be just a beginners guide to Buddhism. However, it is much more than that! It is a gentle guide to Lam-Rim teachings in a very precise way. Geshe Kelsang includes a number of very good explanations and illustrations about his topics at hand. In addition, it has a very contemporary feel to it. Many traditinal Lam-Rim texts and writings tend to be at least 30 years old, so the language and examples aren't always so useful. This text is really an exception-he really did an awesome job writing it. Though it might not be good to introduce someone to Buddhism, it is a great guide to furthering ones study of Lam-Rim.
This book is one of the most enjoyable and helpful books I have ever read. It provides information on how to apply buddha's teachings to your everyday life so that you can remain happy all the time. I highly recommend this book.
