It's the world-building that first drew me in. We've got everything here, including a bureaucracy! Now I know it's real. Peter Sartucci has a good sense for the telling detail: a fortune-teller smells of "desert incense and goats and sweat". I feel as if I could walk among these adobe-walled buildings and climb up the roads through the hills outside.
A world needs people of course. These are wonderfully varied. Royalty and humble entertainers, a powerful wizard pursuing his own ends without regard for the Empire or it people, and a man who is deeply conflicted about his own powers. A sorceress who's hundreds of years old, but has sworn allegiance to the royal line many times. I love multiple viewpoint novels, and here we have a feast of them.
They don't know it, but they're all part of each other's story. The prince just coming into his life as a ruler, the acrobat/actor trying desperately to help his family find a new performance place, mages, generals and all are going to connect.
Finding out how is tremendous fun.
