We get to know things from two points of view: Marcus' and Alejandro's, so the story gets much more enjoyable and less biased. The characters are very well developed and the plot is a good one. There is also the right balance of plain story and sexy scenes, so if you think this is going to be a book plagued with sex scenes, like other porn books I have seen around, you are wrong. Sport of Kings is both sexy and emotional.
If I have to say something not so good about this book, I will say that I found some repetitive sentences and structures. But overall, I really recommend this book if you like fast-paced, sexy books. Another great book, Livia. Keep up with the good job!
