" I cannot put into words how much I disliked this book. After reading Carr's Alienist, I had high hopes for this novel. But for anyone who reads science fiction seriously, you will find this novel laughable. The characters are uninteresting, the plot is silly, and the ending is contrived. He needs to keep to the history and historical fiction and leave the SF to those who know what they are doing. "
