Captures the nature of the dilemma extremely well . Tuch is very insightful in his observations about this syndrome.  Having been involved in this kind of relationship myself in the past, I can say that his description of how these relationships progress is VERY familiar.  This book will provide well-needed understanding by all involved parties.  This understanding is crucial in order to get unentangled from this kind of relationship...or transform the unhealthy agendas/perspectives that often permeate the relationship and give the relationship a chance to either end or work out

A Poor Book . I began reading this book in a local Christian bookstore. I was utterly shocked at the bad reasoning that is passed off in this book as "proof" that popular trends, including Pokemon and Harry Potter, as evil.    The author first claims that the vomiting and dizziness that some people experience while watching Pokemon is "proof" that Pokemon is Satanic. It's called 'epilepsy', Jacobs, and there were 1.4 million people who suffer from it in 1996.     She then claims that Pokemon "encourages" its players to cheat using the GameShark - a cheating device for those who don't know. This indicates lack of knowledge on her part. First of all, the GameShark is not a Pokemon phenomenon; you can cheat on almost any videogame. Secondly, I rather doubt that cheating on a videogame is proof of "bad morals" on the part of the gamer.    Jacobs concludes her Pokemon section by citing an instance when a fourteen year old Pokemon fan assaulted someone in his high school in order to obtain a Pokemon. Since when, exactly, has the bad behavior of one teenager reflected on an entire franchise? That's like saying that ALL Christians are responsible for the dishonest practices of televangelists like the Bakkers and Robert Tilton.    The section covering Harry Potter contains similar bad logic. Jacobs cites a quote from a young fan of Harry Potter who claims that they want to "become a witch", thereby reasoning that the entire Harry Potter franchise must be evil because of the acts of one fan.     She also concludes that Harry Potter "must" be evil because it is about witchcraft. The Bible contains historical accounts of entire civilizations being eliminated and many other violent subjects, but that doesn't mean that anyone who reads the Bible is murderous. It means that the Bible happens to contain violent passages.    Jacobs is supposed to prove conclusively that Harry Potter, Pokemon, Magic cards, and other trendy fads are Satanic, but I think that her arguments are quite weak. She more proves that these fads are NOT Satanic than she does prove that they are
