"Blue nights" sono le ore lunghe e luminose della sera che a New York preannunciano il solstizio d'estate, "l'opposto della morte del fulgore, ma anche il suo annuncio". Sono passati sette anni da quando Joan Didion e John Gregory Durine festeggiavano il matrimonio della figlia Quintana Roo nella cattedrale di St. John the Divine in Amsterdam Avenue. Joan Didion ripensa a quel giorno, ai gelsomini del Madagascar nei capelli di Quintana, al fiore di frangipani tatuato sulla spalla. I ricordi rievocano istantanee dell'infanzia di Quintana: Malibù, la scuola di Holmby Hills, la California Meridionale e le sue stagioni "che arrivano in modo così teatrale da sembrare colpi di un destino inatteso". I ricordi spingono Joan Didion a interrogarsi sul suo essere madre, ora che la figlia non c'è più. A rileggere ogni singolo evento della vita di Quintana alla ricerca di segni che forse non aveva voluto vedere. A fare i conti con la propria, inaspettata vecchiaia. Come "L'anno del pensiero magico", "Blue nights" colpisce per la precisione chirurgica con cui parla del dolore.
Joan Didion was an American writer and journalist. She is considered one of the pioneers of New Journalism along with Gay Talese, Hunter S. Thompson, and Tom Wolfe. Didion's career began in the 1950s after she won an essay contest sponsored by Vogue magazine. Over the course of her career, Didion wrote essays for many magazines, including The Saturday Evening Post, Life, Esquire, The New York Review of Books and The New Yorker. Her writing during the 1960s through the late 1970s engaged audiences in the realities of the counterculture of the 1960s, the Hollywood lifestyle, and the history and culture of California. Didion's political writing in the 1980s and 1990s often concentrated on the subtext of political rhetoric and the United States's foreign policy in Latin America. In 1991, she wrote the earliest mainstream media article to suggest the Central Park Five had been wrongfully convicted. In 2005, Didion won the National Book Award for Nonfiction and was a finalist for both the National Book Critics Circle Award and the Pulitzer Prize for The Year of Magical Thinking, a memoir of the year following the death of her husband, writer John Gregory Dunne. She later adapted the book into a play that premiered on Broadway in 2007. In 2013, she was awarded the National Humanities Medal by president Barack Obama. Didion was profiled in the Netflix documentary The Center Will Not Hold, directed by her nephew Griffin Dunne, in 2017.
