Emperor - The Death of Kings -

A book by Conn Iggulden. It's the second by him I read after "The Mosaic of Shadows"... Wait a second... No, that one was written by Tom Harper. Funny, I had the impression the two books were written by the same person.
Anyway, I liked both. Now that I think of it, "The Death of Kings" lacks a central story, as opposed to "The Mosaic of Shadows". The former tells a part of Julius Caesar's life, mentioning several unrelated successive battles, while the latter is focused on one particular event, the siege of Byzantium by a "friendly" allied army.
C. Iggulden describes the life of Romans - civilians, politicians and soldiers - in an precise and accurate way.
A good read if you are interested in ancient Rome and Caesar.
