I have now started work on this. The setting is the British Isles between 1914 and 1920, with a special concentration on the Celtic nations of Great Britain.
Don't get too excited too quickly. Only the first chapter of the first volume of the Trilogy is complete. It will be at least volume two before a Scottish dimension emerges and fans of militant Welshmen might have to wait even longer...Looking forward to the Welsh occupation of London and the burning of Newcastle by the Highlanders
