I'm a member of the Historical Novel Society which reviewed The Good Thief, book 4 of the Westphal period mystery series, and all three books of The Arrius Trilogy, Sacramentum, Legacy and Enemy of Rome. The reviewer for Legacy ended by saying, "Recent military realities are reflected in this book and contribute to its intensity. It is a gripping read. I am looking forward to the third book in the series." For the final book the reviewer had this to say: "Holtry sustains in this third novel of the trilogy all the suspense and complications we have come to expect from the first two. His knowledge of military strategy, both Roman and tribal, is conveyed with passion and understanding. A compelling and enthralling read."
