Lysette's singing career finally begins to take off, now that she has become a citizen of Columbia through marriage, and she is invited to sing for the president, then to teach and sing in a concert series in Deseret.
Though Modesitt paints a rich tapestry of everyday life in this alternate timeline, the story tends to drag. Action scenes are few and far between. Modesitt also seems to expect us to remember all the political machinations and motivations from the first novel, and it's been a while since it came out. I'd suggest reading the two one sitting, so to speak.
