Query: I waited too long Under the Banner of Heaven

I am enthralled with the subject of Polygamy and this is a well written book . . . very clinical, informative, factual and dry book - which is why I gave it 2 stars. If the author had cut it down it would have earned three stars from me. I need just a little more heart and soul for me to grant it a better star rating. I enjoyed immensely the 19th wife. I understand this was not that kind of book, but I put this book away 60 pages from completing it, because it had lost my interest and that was not the case with the 19th wife, not even once.
