By making one of the Roman officers and one of the Briton elite followers of “the Way” (as an early name for Christianity) Seddon introduces a new dynamic to this retelling of the Boudiccan Rebellion of AD 60. It works, mostly. As with most you-are-there historical fiction, principal characters pop up in illogical places and slip through the fingers of fate with amazing ease, but that’s mostly to keep the plot coherent. The combat is as gruesome as expected for that time without dwelling on the gore. Motives are fairly and honestly explored on all sides. Many historical figures have cameos. Good pace.
Quibble: Yes, many authors are willing to place the apostle Paul in Briton at about that time, but his life could just as well have ended with his first visit to Rome.
Neat opening: Luke starting the third volume of his works of early Christian history, of which only the first two are known (the Biblical books of The Gospel According to Luke and The Acts of the Apostles).
A very good read.
