From Wikipedia
The Skystone is a historical fiction novel written by Jack Whyte, which was first published in 1992. The story is told by a Roman Officer called Publius Varrus, who is an expert blacksmith as well as a soldier. In the early fifth century, amid the violent struggles between the people of Britain and the invading Saxons, Picts and Scots, he and his former General, Caius Britannicus, forge the government and military system that will become known as the Round Table, and initiate a chain of events that will lead to the coronation of the High King known as Arthur.

From Library Journal
During the days of the decaying Roman Empire, the legions of Britain struggle to preserve the ancient principles of loyalty and discipline-virtues embodied in the Roman general Caius Britannicus and his friend Publius Varrus, an ex-soldier turned ironsmith. Whyte re-creates the turbulence and uncertainty that marked fifth-century Britain and provides a possible origin for one of the greatest artifacts of Arthurian myth-the legendary sword Excalibur. Strong characters and fastidious attention to detail make this a good choice for most libraries and a sure draw for fans of the Arthurian cycle.
