This is Book 4 in the Regina Shen series by author Lance Erlick. I have read the first three and I have liked all of them.  For those who have not read the earlier books in the series I will not tell of the book itself. But rather of the great story that the author has given us in this series. This is the continuation of Regina Shen looking for her sister. Anyone who loves science fiction will like this series. The story and the writing is wonderful. I give this book a 5/5. I really recommend this series.
