Query: Such a sad book

The authors seem desperate for credibility. One author even posted two 5-stars reviews for themselves. Most people can find a place with access to Amazon to post their own opinions. The sad fact is that not one academic has sanctioned this book. Instead an unknown author and Anastasia supporters also post two 5-star reviews. It would seem reasonable to request that have an Ivy League scholar voice an opinion. I don't doubt they worked hard but they are wrong-headed. I did not enjoy this book or find anything substantial in this account.
