This, the third book in James Mace's series is a little flat compared to the other two. The problem is that the Hero, Artorious, whilst well painted in the previous two books and allowed to roam in our imaginations, has been slightly curtailed. This means that the "sex as a means of keeping interest in the book" is more noticeable as are some of the more glaring and repeated spelling errors. e.g., I am positive that the Romans had a lot more "Provincial" Governors than they appear from these books to have "Provisional" Governors.
Having said that, in all it is a good series but could be improved by more fleshing out of Artorius and a bit more fleshing out of the Imperial power plays which seem to fluctuate between vague and overplayed but are mainly just whetting the curiousity rather than satisfying it and making the reader care about it.
In all a good read but in comparison to the previous two, "Could do better" as my old teacher used to say, we have proof of that by Books 1 and 2.
