This is a really short book, so my review will also be short.
The Treasure Principle is absolutely 100% not a "wealth and health doctrine" book. It is a wake-up call to when, where, and how much we should be giving according to the Word. Randy Alcorn lays out six "Treasure Principles" in his book to consider when giving, and backs them up with Scriptural examples. Like I said, this is a very short book; I read it in about an hour. But it packs quite a punch! From the 2nd page on I was convicted. My church read this book together, so we also had the accompanying study guide, which will help the reader analyze their own giving in light of the book's examples. Even as a standalone, I definitely recommend this book. While giving clear, concrete examples, the text is never bogged down in long quotes or endnotes. It's very readable; not dry at all. At the end of the book, the author presents 31 questions with corresponding Scripture for the reader to meditate on. And this probably won't surprise you: 100% of the royalties from sale of this book goes into missions!
