A Stoic philosopher and divorcée, Adora Hazzard lives a contented life on New York City’s Upper West Side. Having discovered that the secret to happiness is to desire only what you have, she’s applied this insight to blissful effect: relishing her teenage daughter, the freedom of being solo, and her job as a moral tutor for the twin boys of an old-money family. She’s even assembled a “coven” --- like-minded women who live on the same floor in the legendary Ansonia --- and is making active efforts to grow its membership. Adora’s carefully curated life is humming along brilliantly until a chance meeting with a handsome stranger. Soon, her ordered world is upended by black-market art deals, secret rendezvous and international intrigue…and her past lands like a bomb in her present.
