I don't know. I loved his first series, but this one seems to be getting worse as it goes on. The Raven was just okay, and I dragged through the pages of this one hoping that something would happen. Raven whines, the Prince broods, they have sex and repeat for over two-thirds of the book. When there finally is some action, it's over so fast, and then the book was over, leaving a cliff-hanger. I will say that the cliffhanger seems to indicate that then next book will be much better, or, at least, has that potential. 
 Sylvain Reynard is a decent writer and his love of art and Florence shines through. I just wish there was a better story here.
