I’m a little confused here as I’m not quite sure what you’re trying to achieve with your blog post.
Do you think your readers have read your book? If yes, then you probably won’t arouse their curiosity with a title that suggests you highlight the key points. In this case you may want to consider rephrasing your title and not refer to the book, but more to the benefits people will get from your post.
Some of your titles suggest that you want to write about what’s wrong with the book. This can be a good approach and stir up some debate. In this case, you might want to go much stronger and go for something like:
5 Critical Reasons Why “The Secret Book” Is an Utter Waste of Your Time
5 Critical Reasons Why “The Secret Book” Should Be Banned
This are just a few quick ones of the top of my head – they could probably be improved. Let me know what direction your heading in and how your readers will benefit from your post, and we can brainstorm a little more.
Enchant readers. Woo customers. Win business.
