Freddy and Fredericka

Blurb

Freddy and Fredericka is a 2005 satiric novel by Mark Helprin.
Freddy and Fredericka are a British royal couple similar to Prince Charles and Diana, Princess of Wales. The two are sent to America on a comic adventure to fulfill a quest to achieve Freddy's destiny.
In an interview, Helprin said that the idea for the story originated while he was in a restaurant in Portland, Oregon, while on book tour with his family to promote A Soldier of the Great War. The restaurant had a window through which patrons could see some people cooking and others washing dishes. One of Helprin's daughters asked if it was the Prince and Princess of Wales, who were in the news at the time, washing dishes.
