A Romantic Fantasy in 2 Acts. Clair is a former aviatrix, now in her 40s and far removed from Paris, the scene of her flying. Henri, her long-estranged and wealthy husband, visits her in Kansas City after a 20-year absence. He informs her that a museum is interested in their airplane, "Clair de Lune." The opera addresses serious themes: love, aging, and the irreconcilable demands of independence and security of its unconventional heroine.
