In the late nineteenth and early twentieth centuries George Griffiths was as well known and, according to some experts, as popular as that other exemplar of the early British scientific romance, H. G. Wells. 'Olga Romanoff', the sequel to 'The Angel of the Revolution, ' tells of a future Earth in which the nation states that had once warred amongst themselves are given full self determination when the Aerians, the descendants of 'The Brotherhood of Freedom, ' who have policed world peace for more than a century, decide they are mature enough to have outgrown war. The inevitable consequence is, once again, warfare. However, a message from Mars warns of impending doom and the rekindled enmity must be set aside to save mankind. Both 'Olga Romanoff' and 'The Angel of the Revolution' are both available from Leonaur in hardcover and softcover edition
