Mormons believe that the 2/3rds of the angels that chose not to follow Satan are to be given a second chance by being born and allowed to choose again. Your book at first glance mirrors a pre-existent being waiting to be born. That is not a biblically-based doctrinal truth. Some will shy away from your book because of that.
Did you at least research how your book’s premise might be confused for Joseph Smith and his bunch.
Otherwise, I do apologize for posting my remark in a sharp fashion.
I am not really well versed on Mormon theology, but it seems that the 2/3 of the angels chose properly the first time. Why would they need another chance?
