Princess Sophia of Prussia travels to Russia to meet Peter, her cousin who is the heir to the Russian throne. Peter is a difficult person to deal with and Sophia has numerous challenges and obstacles to face before she is accepted as Peter's future wife.
Sherry Ficklin includes having to challenge Peter in sports, but letting him win, allowing him to treat her badly on occasion, and an incident in which she was poisoned by someone who favored a rival princess. On Sophia's conversion to Russian Orthodox, she took the name Catherine. History recalls her as Catherine the Great.
Sherry admits that Queen of Someday does not strictly follow historical facts. She wondered what would have to happen to a teen-aged girl to turn her from a child into one of the strongest women in history.
I couldn't put it down.
