This book SCREAMS CSI aesthetic, but with the twist of fallen angel (could it be like the hit tv show Lucifer?). The book cover, is very scientific like, and haves an angel. I do have some troubles trying to figure out why did the plot leave to mention for the last sentence that it involves fallen angels???, I am no expert but it should be within the first four sentences!!! Nevertheless, this book uncovers a lot of death and mystery with a sprinkle of science fiction. Very good! just wished the book cover connected more directly with the plot!
