Suggestion 4. Look at the His Secret Obsession book review and who actually wrote these ideas. Does the testimony seem familiar? Do they seem to come from the author's friends or family to help increase the score? In general, if the meaning of the book is general or not very deep (depending on the site), the book may be general and not very deep. You can avoid this by reading reviews on multiple sites instead of focusing on just one. Take a look at sites like amazon, ebay, google etc. Amazon often has a very good reviewer.
