The Wings of Mercury (Imperium Volume 2, Book #1)

A New War. A New Enemy.
Nine years ago, Lt. Commander Ky, a test pilot from the future, was flung back in time to a world that never existed. In this world, Carthage won the Punic Wars and Rome was all but destroyed, pushed back to a corner of the British Isles. That war is over. With Ky’s help, the Romans formed a new Britannic Empire, defeated the mighty Carthaginian Empire, and set up a new paradigm in Europe.

For five years, Britannia has led the western world into peace. They have helped the recovering people from new alliances and nations, creating a more or less unified Europe. But the time of peace has ended. Shattered by a sudden, unprovoked attack from the east, using weapons equal to those developed in Britannia, war has returned. Now, Britannia rallies the western countries into a new Western Alliance to stave off the eastern threat.

The first book in a six-book sequel series to Volume 1 of Imperium.
