Quick recap
Caesar reaches Egypt chasing Pompey, fights the Alexandrian war and gets involved with Cleopatra. Then he beats the last Republicans in Africa and Spain, led by Metellus Scipio, Cato, Labienus and Pompey's sons. At his peak, torn between his duty to Rome and Cleopatra, Caesar is assassinated on the Ides of March by Brutus, Cassius and the Liberators. His will names the heir: Octavian, his 18-year-old great-nephew, a promising young man who turns cold and vengeful. He fights Mark Antony for power, Cicero is killed, and the two end up allied against Caesar's murderers. The book ends with the battle of Philippi, in 42 BC, where the armies of Brutus and Cassius are defeated.
