It’s an earlier time in Riverside. Diane, Duchess of Tremontaine, is trying to maintain her husband’s wealth and estates. Young Micah makes friends across a gaming table at the University with her mathematical prowess. And disgraced trader’s daughter Ixkaab Balam arrives from overseas, keen to practice her swordcraft. I’m finally turning my attention to Tremontaine, Ellen Kushner’s adventure in world-sharing and serial publishing.
