Joan Didion’s The Year of Magical Thinking faces the harrowing absence of death with systematically beautiful language.
On most surface levels I seemed rational. To the average observer I would have appeared to understand that death was irreversible. I had authorized the autopsy. I had arranged for cremation. I had seen the ashes placed in the wall and the marble plate replaced and the service held. I had done it. I had acknowledged that my husband was dead. 
Later I realized that my immediate thought had been that I did the ritual. I did it all. And it still didn’t bring him back. Bringing him back had been through those months my hidden focus, a magic trick. 
Read this book a few years ago…struck me with its timeless take on the passing of loved ones. Yet she urges on.
And conveys that understanding with eyes wide open.
