"Very captivating."
This is great because it is informative yet novel-like.
This story is mostly informative. It is mostly a defense for Cleopatra, but it tries to summarize everyone's point of view about her (including negative views). The author is mostly unbiased about Antony, Cleopatra and Caesar. She may be biased against Octavian, but she talks little about him.
Enjoyable
Yes, of course. The Battle of Actium, the tale of Antony fishing and the final moments of Antony and Cleopatra.
