I've read Holland's Rubicon early on in my ancient Roman reading and plan to read it again now that I really appreciate the topic. My favorite book to date is First Man in Rome. I'm on book 4 in the series and love them all. I'm also reading Everitt's Augustus and enjoy it immensely. I plan on getting I, Claudius next even though I've seen the BBC TV series. There's many more books on my list I'm going to read. I just can't get enough.
