The Blood of Gods: Emperor series: Book 6

Julius Caesar has been cut down. His blood stains the hands of a cabal of bold conspirators, led by famed general Marcus Brutus—whom Caesar once called a friend. Have these self-proclaimed liberators bravely slain a power-mad tyrant or brutally murdered the beloved Father of Rome? Hailed as heroes by a complicit Senate and granted amnesty, the killers eagerly turn toward plotting the empire’s future under their control. But Caesar’s death does not rest easily with all of Rome. For two men whose bonds of friendship, family, and fidelity to the emperor are unbreakable, the shocking assassination is nothing less than treason. And those responsible must pay with their lives.
