I would classify this book as an allegorical Christian thriller and I really looked forward to reading it after hearing good things about some of the author's other books. Unfortunately, I was not impressed by Black. It was unnecessarily long and I found myself rather bored at times. The allegorical aspects seemed alternately too obvious and too convoluted, leaving me to wonder at the author's intent. The "great romance" allegory struck me as cheesy and, as a Christian, I was left wondering what a non-Christian would think.
Black is part of a series and perhaps reading the entire series would make a difference. I would also like to comment on story format. My copy of Black included the graphic novel version. I did find the graphic novel format much more entertaining and a more appropriate medium for this story.
Rating: 2 out of 5 (for the novel); 3 out of 5 (for the graphic novel)
