In 1949, during her junior year abroad in Paris, Jacqueline Kennedy Onassis bought several inexpensive paintings of Marie-Antoinette by a little-known 18th century female artist. She also had a romantic relationship with Virginia vineyard owner Lucie Montgomery's French grandfather - until recently, a well-kept secret.

Seventy years later, Cricket Delacroix, Lucie's neighbor and Jackie's schoolfriend, is donating the now priceless paintings to a Washington, DC museum. And Lucie's grandfather is flying to Virginia for Cricket's 90th birthday party, hosted by her daughter Harriet. A washed-up journalist, Harriet is rewriting a manuscript Jackie left behind about Marie-Antoinette and her portraitist. She's also adding tell-all details about Jackie, sure to make the book a bestseller.

Then on the eve of the party a world-famous landscape designer who also knew Jackie is found dead in Lucie's vineyard. Did someone make good on the death threats he'd received because of his controversial book on climate change? Or was his murder tied to Jackie, the paintings, and Lucie's beloved grandfather?
