For an American trying to understand an Eastern religion, it is difficult to overcome new concepts and vocabulary. While trying to do this, I found myself missing the key points. Since this book was written for a younger audience, the language helps you gain a good, basic understanding of Sikhism. After, adults, or young adults, can progress to denser texts.
This is a fairly short book. Let this be an indication that it will not get caught up in philosophical discussion. It merely gives you the facts about this religion. It explains the history, some of the characteristics (like the 5 k's), and the special occasions (all of which seem to deal with the reading of the "Guru Granth").
In the back of the book is a glossary to help you remember and work with the text. I found the book written in such a way that I did not need to refer back to it.
I would recommend this book to anyone wanting to know about Sikhism.
