I don't know what to say about this book. There were just so many good things about it. I don't have one negative to say. I
The character were well done. I cared about what happened to all the main characters, even if I did not like their role in the story. I wanted to know what happened to them. The two main characters Aiden (the white slave) and Kai (the black master) were very believable for the time period that the story took place in. Barnes developed the characters (all of them) nicely and seemed to put a lot of thought in what role they played in the story.
I also like how Barnes included references to historical figures in the story (Shaka Zulu, Mozart, Da Vinic) and what their role would have been in his alternative history where Islam dominates.
Another plus is that Barnes did not sugar coat the possibility of Islamic slavery. He did not make it seem that slavery in an Islamic America would have been better and more humane. In fact Lion's Blood illustrates that it would have been the same but religious orientation different.
At the end I could not put this book down and basically read the last 200 or so pages in one sitting. I even shed a tear at the end. It's a great story of friendship and slavery. I am going to put the sequel on my wish list.
