There is absolutely nothing unreasonable about being irked by an unauthorized biography and/or tribute book when it comes to your our own family. That doesn't mean that the publisher did anything legally wrong and it doesn't mean that you, as a reader, should or shouldn't buy it. I'm not sure why we need nine pages of forum entries to debate it. It's just a natural reaction. It happens nearly every week in other entertainment mediums. Stephanie, apologies.
