I'm not sure if I could have formally sat down to read this book, simply because it is so very long. When the audible became available I jumped at it.
The audible is 96 chapters and 31 +- hours long but the narrator was very good.
The story itself, for me, initially dragged in the first chapter or two when we are first introduced to Phedre. After that, it quickly starts to pick up the pace. It's a complex story of political intrigue with all sorts of interesting characters and unexpected plot twists.
I am seriously considering listening to the next in the series.
