A succinct, yet thorough, summation of Jehovah's Witnesses' beliefs. There are discussion questions, to encourage you to consider what you're learning and reevaluate—the obvious aim is not to indoctrinate, but to produce a discourse. Each chapter is also summarized at the end, which is helpful. To paraphrase JK Rowling (specifically her book, The Half Blood Prince), you don't want to read something just for it to "slip through [your] brain without leaving the slightest trace of meaning behind".
For each point they make, there is a relevant scripture cited. If you're interested in the study of religion, this could definitely be called thought-provoking. Even if you don't agree with their beliefs, I think you can see for yourself that they didn't come from nowhere. I personally found it to be a fascinatingly insightful view into the Bible. You learn things you've never heard of before, and the most surprising thing is, when you look them up yourself, you find them to be true. They aren't misleading anybody by deliberately misconstruing the meaning of the scriptures to match their beliefs. There's an amount of honesty that is, frankly, quite refreshing. It really is well-researched, in my opinion.
However, the writing style is a little blunt, and I understand why that may be perceived as forceful. If you aren't looking to change religions, you might find yourself a little insulted. But I will say that one should keep in mind the point of this book: to learn what the Bible says is true. I think they succeeded on that front. You're still meant to consider for yourself whether or not to adopt Christianity based on its own merits. They're merely proposing some new ideas about an old religion, and really, if you were possessed of even the least amount of brain cells, you could decide on your own what you think about that.
