Imperium, a kind of historical political thriller, is mainly about the life of Cicero (up to when he becomes a consul) through the eyes of his slave, Tiro. I really enjoyed this book, because a lot of books that take place during the Roman republic and empire tend to be centered around the military men, which Cicero is decidedly not.
I enjoyed the political intrigue quite a bit, and I like that the story was told through the eyes of his slave/freedman/secretary. While the story takes some liberties, as I would assume any historical fiction piece would do, I enjoyed looking up some of the aspects of the book to see how the book compared to known historical facts.
I look forward to the next book in the series, and other works of Harris.
