I was very disappointed in the book. I'm not sure how to explain this without giving away too much of the book. So, if plan on reading the book and you want to be surprised read no further.....The book is about the search for the "messiah" by matching his DNA. In chapter 19 they search their own database. In chapter 21 they are surprised when they find the messiah's DNA in someone else's database. The problem is the DNA was entered into their own database in chater 10. So, why didn't they find it when they searched their own database?
