Searching for the tomb of the legendary First King of Britain shouldn't lead to anything but more professional ridicule for archaeology professor Belinus Carter. Instead he and his wife Emily, a secret agent for the Royal British Protectorate, are drawn into a political conspiracy that leads all the way to the top of British society. Fighting for their lives and hunted by the government of the country they are sworn to protect, the Carters and the Royal British Protectorate must go on the offensive. Using the secrets of the tomb of King Brutus they will battle to restore the country they love and defeat it's darkest foe - an enemy from within that threatens the very fabric of Britain and everything it stands for. Politics, archaeology, mythology and espionage crash together in Sovereign Nation.
