- Rubicon by Tom Holland
- SPQR by Mary Beard
- Dynasty by Tom Holland
- Caesar by Adrian Goldsworthy (more of a bio on Julius C, a bit drier than the above, has section on Alesia)
Thank you for the recommendation of Rubicon. I enjoyed reading through this thread so I thought I'd take you up on your recommendation. It was this first history book I've read in probably a decade, so I wasn't sure if I was going to enjoy it but I absolutely loved it.
