The Camulod Chronicles, Book 1
by Jack Whyte

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. The Skystone 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.
