The premise is a fine idea, but unfortunately the story suffers from being set in a very messy historical time. Dozens of players are rapidly introduced, leading to just as rapid confusion. While the story does gel somewhat around the characters of Roxane and Euridyce, it is hard for the reader to get to grips with the wider political situation. Where the book shines is when dealing with the culture shock of people from ancient civilisations being suddenly introduced to things like steam engines, refrigeration and modern views on gender equality. There is a wide ranging discussion of slavery which manages to be quite interesting.
This book is part of the wider Assiti Shards Universe, though it can be treated as a singleton.
