Fall of Giants (The Century Trilogy #1) by Ken Follett
It is 1911. The Coronation Day of King George V. The Williams, a Welsh coal-mining family is linked by romance and enmity to the Fitzherberts, aristocratic coal-mine owners. Lady Maud Fitzherbert falls in love with Walter von Ulrich, a spy at the German Embassy in London. Their destiny is entangled with that of an ambitious young aide to U.S. President Woodrow Wilson and to two orphaned Russian brothers, whose plans to emigrate to America fall foul of war, conscription and revolution. In a plot of unfolding drama and intriguing complexity, "Fall Of Giants" moves seamlessly from Washington to St Petersburg, from the dirt and danger of a coal mine to the glittering chandeliers of a palace, from the corridors of power to the bedrooms of the mighty.
