It is spring in the year 118, and Gaius Petreius Ruso has been stationed in the Roman-occupied province of Britannia for nearly a year. After his long and reluctant investigation of the murders of a handful of local prostitutes, Ruso needs to get away. With that in mind, he has volunteered for a posting with the army in Britannia's deepest recesses--a calmer place for a tired man.
But the edge of the Roman Empire is a volatile place; the independent tribes of the North dwell near its borders. These hinterlands are the homeland of Ruso's slave, Tilla, who has scores of her own to settle there: Her tribespeople are fomenting a rebellion against Roman control, and her former lover is implicated in the grisly murder of a soldier. Ruso, filling in for the demented local doctor, is appalled to find that Tilla is still spending time with the prime suspect. Worse, he is honor-bound to try to prove the man innocent--and the army wrong--by finding another culprit. Soon both Ruso's and Tilla's lives are in jeopardy, as is the future of their burgeoning romance.
Terra Incognita shines light on a remote corner of the ancient world, where Ruso's luck is running short--again.
