The Empress of the Last Days is the final volume of the remarkable trilogy that began with Astraea and The Pretender. A group of friends, Corinne, Theodoor and Michael, bring together their talents and knowledge to uncover the hidden story of Pelagius's royal marriage. As a result of their investigations, Michael finds himself journeying to Barbados, to meet the last descendant of the marriage of Pelagius and Elizabeth of Bohemia - a young black scientist who, unknown to herself, has a serious claim to be considered the rightful queen of England.

In this impressively far-reaching novel, Stevenson considers the transformative moments in people's lives and, in doing so, creates a paean to love, trust and history.
