The war in Africa is over and the rebel cause hangs by a thread. With opposition to Caesar now led by Labienus and by Pompey’s sons in Hispania, Caesar is one step from ending the civil war that has plagued Rome for years.

Before the war can be pursued, though, Caesar has matters to attend to in Rome. And against a backdrop of glorious triumphs and civil friction, the general’s old warhorse Marcus Falerius Fronto begins to uncover a series of events that may have a cause in common. Investigation, however, is sidelined as necessity finally draws everyone across the sea to the crucible of war once again.

In Hispania the clouds gather, for though the rebels may have been pushed into a corner, they are far from beaten. With the great name of Pompey and the tactical genius of Labienus on their side, Caesar must fight hard to win the day. Fronto and his friends must give all they have now, for the prize for this campaign is the ultimate one: the republic itself.
