Road to Damascus is a Bolo novel by John Ringo and Linda Evens. It takes place on the planet Jefferson, an world allied with the Concordiat.
When a ruthless political regime seizes power on a world struggling to recover from alien invasion, a former war hero finds herself leading a desperate band of freedom fighters. Kafari Khrustinova, who fought Deng infantry from farmhouses and barns, finds herself struggling to free her homeworld from an unholy political alliance, headed by the charismatic and ambitious Vittori Santorini, which has seduced her young daughter with its propaganda and subverted the planet's Bolo, using the war machine to crush all political opposition. To free her homeworld, Kafari must somehow cripple or kill the Bolo she once called friend. Unit SOL-0045, "Sonny," is a Mark XX Bolo, self-aware and intelligent. When Sonny's human commander is forced off-world, Sonny tries to navigate his way through ambiguous moral and legal issues, sinking into deep confusion and electronic misery. He eventually faces a dark night of the soul, with no guarantee that he will understand—let alone make—the right decision. And caught in the middle of this volatile battlefield is Yalena Khrustinova, Kafari's young daughter. Will she open her eyes in time to save herself—and millions of innocents—or will Santorini's relentless brainwashing campaign continue to blind her while the tyrant engineers the ultimate destruction of a helpless and enslaved population
