Dynasty: The Rise and Fall of the House of Caesar by Tom Holland

Author and historian Tom Holland returns to his roots in Roman history and the audience he cultivated with Rubicon—his masterful, witty, brilliantly researched popular history of the fall of the Roman republic—with Dynasty, a luridly fascinating history of the reign of the first five Roman emperors.
 
Dynasty continues Rubicon's story, opening where that book ended: with the murder of Julius Caesar. This is the period of the first and perhaps greatest Roman Emperors and it's a colorful story of rule and ruination, running from the rise of Augustus through to the death of Nero. Holland's expansive history also has distinct shades of I Claudius, with five wonderfully vivid (and in three cases, thoroughly depraved) Emperors—Augustus, Tiberius, Caligula, Claudius, and Nero—featured, along with numerous fascinating secondary characters. Intrigue, murder, naked ambition and treachery, greed, gluttony, lust, incest, pageantry, decadence—the tale of these five Caesars continues to cast a mesmerizing spell across the millennia.
