Marching With Caesar-Praetorian

In Volume XVIII of the internationally bestselling Marching With Caesar series, Marching with Caesar-Praetorian, Gnaeus Volusenianus Pullus finally returns to Ubiorum after accomplishing his task of securing the Pullus family fortune, which had been endangered because of his time as a hostage in Britannia . Upon his arrival he is greeted with a mysteriously vague order to report to Germanicus Julius Caesar in Rome.
On his arrival, he is informed that, in exchange for the favors and protection that Germanicus has previously extended to Gnaeus, which Germanicus provided both in recognition of Gnaeus' father's service to himself and as part of Titus Porcinianus Pullus' final wishes, Gnaeus will be required by honor to repay this patronage and protection with service, a Roman tradition that extends back centuries.
That service comes in the form of Germanicus reassigning Gnaeus to the Praetorian Guard as the commander of the Second Century of the Second Praetorian Cohort, with the mission of gathering information on the actions of the Praetorian Prefect, Lucius Aelius Sejanus, whose power and influence with the Imperator Tiberius is growing at a rapid, and to Germanicus and several of the leading families of Rome, a dangerous rate.
As Gnaeus Pullus will learn, while the challenges and dangers are unlike anything Gnaeus has faced before on the battlefields of Germania, the hazards that duty as a Praetorian Guard brings, not just to himself but to his new family, as well as his clerk and friend Alexandros Pullus, are no less real, nor less deadly, and in Sejanus, Gnaeus will face an adversary whose ruthlessness makes him the most dangerous the Centurion has ever faced.
