Having grown up intrigued by the mystery of the ninth legion I was keen to read a modern take on it and found this very readable and informative, especially with the appendix. At one stage it did feel rather like the Titanic! but that was unavoidable given the subject. The switch from Rome to Antioch to York was very effective and gave it a fast pace. It is a fiction read but I would definitely recommend it, especially to anyone who thinks they have all the answers!
