Question: What was the name of Sand's book where the main characters can be interpreted as Sand and Chopin?
Sentence: In 1847 Sand published her novel Lucrezia Floriani, whose main characters—a rich actress and a prince in weak health—could be interpreted as Sand and Chopin; the story was uncomplimentary to Chopin, who could not have missed the allusions as he helped Sand correct the printer's galleys.
Answer in sentence: yes
