Rich, multi-layered and epic in scale. All my favorite things: societal boundaries, beliefs, emotional depth and engaging characterizations. The worldbuiling is extraordinary as are the range of people inhabiting it. Both Kieran and Ash undertake journeys and their character arcs are detailed and wide. An unlikely love affair that is tested and the barriers dissolved.Favorite quote:""He's -- he's pure, not in the sense of innocent, but in the sense of -- distilled, wholly himself. Pure iron, pure diamond, pure rage. There's nothing like him in the world, and never will be again after him, I think."--Ch. 27"
