Westmark trilogy 03 - The Beggar Queen

The Beggar Queen (1984) is a fantasy novel by Lloyd Alexander, the concluding book of a series often called the Westmark trilogy.
The series has been called "historical fantasy, set in a time much like our 18th century". Another review has called Westmark of the second volume "an imaginary kingdom with a post-Napoleonic cast".
Mickle, once a common street urchin, is now the queen of Westmark. The kingdom is thriving, yet at the same time, it is strangely restless. Ghosts of the past lurk everywhere. The evil minister, Cabbarus, once banished from Westmark, is now plotting to seize the throne. Theo remembers a time when he was the famed Kestrel, fighting battles that threatened to kill his soul. Now he once again must join in the struggle. Who will at last command the fate of Westmark?
One answer to that question is the people. The common people, mostly anonymous, rise up at the end, making the final overthrow of Cabbarus possible.
The book raises moral questions, especially about choices, the effects of having power, and the evil that seems necessary to prosecute a war. Theo tries to keep out of the battles in the book, but finds that he can not. He vows to kill Cabbarus. (Theo had once saved his life in Westmark, the first of the trilogy.)
