Audiobook Turncoat's Drum, written by Nicholas Carter, is the first book in the series The Shadow on the Crown. The country is in turmoil in this thrilling historical adventure of the English Civil War. It is 1643, and the struggle between Parliament and the King erupts in the West Country, tearing families apart and setting village against village. But for some, this fight is not only about crown and country: it is far more personal than that.
