Burden’s memoir, which springs from a widely read essay published in The New York Times, describes a fantasy land of wealth and success — perhaps most enviably, her stable and happy marriage. The world Burden inhabits with her husband, James (she has changed his name here, but apparently not much else), is one of Edenic privilege. They live in multimillion-dollar homes in New York and on Martha’s Vineyard, belong to private clubs, have keys to private beaches, kids in private schools.
