Give Me Back My Legions!
Harry Turtledove
 Publius Quinctilius Varus, formerly the governor of Syria, is appointed to the governorship of Germany, a hold-out full of what the Romans thought of as barbarians. During a brief assignment to the Legions in Dalmatia, Varus befriends the Germani auxiliary commander Arminius, unaware that the latter has plans of his own for the Romans occupying Germany.
