Working on a historical novel by Conn Iggulden (which sounds like a pen name, but apparently isn't), Emperor vol. 1, The Gates of Rome1. It's about Julius Caesar, and it's good, but so far veers pretty wildly from the historical record. But maybe that's because this is Young Julius, and the historical record there is about 2 sentences long. Also working on an actual history, "Britain After Rome" by Robin Fleming, which is really interesting because it makes such heavy use of archaeology. Right now I'm reading about The Collapse, that is, Rome's withdrawal from Britain, the breakdown of the economy and what is happening to political authority in that. The author writes about the disappearance of nails from Britain - what happens when that happens.
