The book also deals with another topic that I am not really all that familiar with, Voodoo. Now my very limited "knowledge" of Voodoo comes from an episode of Bones that I have seen a few times. The only thing that really did was make a few of the terms a little bit familiar to me. I found the Voodoo aspect of the book to be very interesting especially considering who is using the spells. There is also a bit of a time ripple that takes place in the book that adds a pretty unique twist.
The reason I only went with three stars is actually tough to explain, the idea of the book was pretty interesting. It really just didn't draw me in as much as I would have liked. I've never really liked reading in accents and there is a bit of that in this book from the Haitian characters. I also had a bit of difficulty understanding the motivation of one of the major bad guys, he had a bit of a conflict of interest and it made it confusing to me why he did what he did (I know it's confusing but saying more would be a pretty major spoiler).
So there are plenty of reasons to check this book out especially if you interested in reading stories involving Voodoo or from the post Civil War era.
