Templum Bellonae

This is actually the main story in a series; it has both prequels and sequels, but this is as good a place as any to start reading. Despite the numerous overlapping pairings, the tone manages to stay relatively faithful to its historical period. And I have to admit that I’m as much of a sucker for Edrington as for Archie Kennedy.

There’s also a reading guide.
