Nope, nope, nope. I was on the fence about this book, as the first one did not inspire a lot of confidence. I understand this is a work of fiction, but when it is discussing doctrine, I need it to be grounded in that doctrine. The first book was made, whole cloth, from the authors imagination, which I was mostly okay with, since there is not a whole lot of literature to refer too.
But this second book, just keeps on going, making up things as he goes along. As far as I got into the book, there was an entity(?) who may or may not be a devil, a terrorist attack, and visions of a daughter in the premortal realm as she is being born. What finally stopped me though was reference to Master Mayhem, which I assume is based on a mis-hearing of Master Mahan, the name given to Cain after he killed Abel, which means "Keeper of the Great Secret," the secret being murder as a means to get gain.
Master Mayhem is mentioned nowhere that I could find, and seems to be something the author added in, because it sounds cool. I'm fine with taking artistic license with source material, I'm not fine with making up doctrine as you go along.
