Sons of Empire - The Imperial Chronicles, #4

The Empire speeds toward a new century, anticipating new heights of prosperity and power but finding its triumphant march forced to a stumble. An official visit from the northman king, Gylles vis Bretagne, is laced with ulterior motives and may lead to a disastrous war. While the supernatural forces of shadow grow beyond the border, elements within the governmental elite tighten the noose. As the crisis deepens, six souls find themselves at the center of it all--six disparate lives, inexplicably yet intricately connected.
