In 2005, Joan Didion published a remarkable, unflinching portrait of grief, The Year of Magical Thinking, about the death two years earlier of her husband, fellow writer John Gregory Dunne.
At 71, he had a heart attack shortly after the couple visited their daughter, hospitalized in a coma. Later, Quintana Roo Dunne Michael improved, but shortly after Didion finished her book, Quintana died of complications from pancreatitis. She was 39.
"That would take a whole other book to do," Didion said at the time. "It's not a book I'm ready to write." Nor was she sure "what form it will take."
At 76, Didion has written that book, Blue Nights. Despite writing that is lovely and wrenching, it is disappointing.
In Magical Thinking, Didion, a novelist, screenwriter, essayist and reporter, put all her talents to use exploring what she called "the shallowness of sanity" after her husband's death and her only child's illness.
It won the National Book Award, reached as high as No. 16 on USA TODAY's Best-selling Books list and was adapted as a one-woman Broadway play with Vanessa Redgrave.
Blue Nights is less focused. It's filled with unanswerable questions. It's less about Quintana, named after a Mexican town, than it is about Didion's growing sense of fraility.
The comparisons to Magical Thinking are inevitable but perhaps unfair. The earlier book also celebrated her husband's life, in the way that the best funerals can be celebrations.
For a parent, the death of a child, at any age, is different.
"When we talk about mortality we are talking about our children," she writes. Then she adds, "I just said that, but what does it mean?"
Which leads to other questions for parents: "Are we saying what it meant to us to have them? What is meant to let them go? Are we talking about the enigma of pledging ourselves to protect the unprotectable? About the whole puzzle of being a parent?"
Quintana was adopted, which poses more questions about the "muddled impulses of adoption."
For the child, Didion asks, "If someone 'chose' you, what does that tell you?
"Doesn't it tell you that you were available to be 'chosen?"'...Are we beginning to see how the word 'abandonment' might enter the picture?"
Didion is at her best on medicine as an "imperfect art," and how doctors retreat into jargon, but she leaves Quintana's illness as a vague mystery.
She writes about "the ways in which we depend on our children to depend on us, the ways in which we encourage them to remain children...the ways in which we remain equally opaque to them."
Blue Nights is opaque, as if Didion was never able to decide what form this book should take.
