Eric Dane’s final book is out today. My Book of Days: A Memoir in Moments, the posthumous memoir the actor wrote in the last year of his life, was released on Tuesday, November 3, 2026. In it, Dane writes openly about his career, his struggles with addiction and sobriety, his family, and the ALS diagnosis that took his life at 53.
Dane was best known as Dr. Mark “McSteamy” Sloan on Grey’s Anatomy and as Cal Jacobs on HBO’s Euphoria. He died on February 19, 2026, less than a year after he went public with his ALS diagnosis in April 2025. The book is his own account of what those final months were like, and it is already the most searched celebrity story in the United States today.
What is Eric Dane’s memoir about?
My Book of Days is a 272-page memoir published by The Open Field, an imprint of Penguin Random House. Dane worked on it with writer Alan Eisenstock during the final year of his life, looking back at the moments that shaped him, from his early acting years to his diagnosis and his family life.
The book is dedicated to his two teenage daughters, Billie, 16, and Georgia, 14, whom he shared with his estranged wife, actress Rebecca Gayheart. Dane spends the final chapter writing about his hopes and dreams for them.
An audiobook version is also available. It is narrated by Jacob Elordi, who played Dane’s on-screen son Nate Jacobs in Euphoria, with Maria Shriver also taking part in the reading. The audiobook runs for five hours and 53 minutes.
The misdiagnosis before the ALS diagnosis
One of the most striking parts of the memoir is Dane’s account of how long it took to get the right diagnosis. He writes that he first knew something was wrong when he started gradually losing the use of his right hand.
“First, I saw a hand specialist, who passed me off to another hand specialist, who sent me to a neurologist,” Dane wrote. The neurologist first thought he was developing some form of neuropathy, and after a series of tests Dane was given a diagnosis of multifocal motor neuropathy, a rare autoimmune disorder that causes extreme muscle weakness.
Dane describes the condition as having a “90 percent effective” treatment. But when he did not respond to that treatment, his doctors began to consider ALS. He then had a lumbar puncture, spinal fluid tests and brain scans before the ALS diagnosis was confirmed, nine months after he first sought help, in 2024.
In the book, Dane calls the diagnosis a “death sentence” and says it felt like the wind had been knocked out of him. ALS, or amyotrophic lateral sclerosis, is a disease that destroys the nerve cells in the brain and spinal cord that control muscle movement. Over time, walking, speaking, swallowing and breathing become harder, and there is no cure.
How he told Rebecca Gayheart
Dane also writes about the moment he told Gayheart the news. In an excerpt published by People, he recalled calling her on the phone and saying, “It’s what we feared.” He wrote that he does not remember a single word he said after that.
Dane and Gayheart married in 2004 and separated in 2018, when she filed for divorce. Even so, she was at his side in his final months, and she has spoken publicly since his death about the book and the man behind it.
Rebecca Gayheart’s first interview since his death
On the morning of the book’s release, Rebecca Gayheart spoke about Dane’s final week on Today in a pre-recorded conversation with Maria Shriver. It was her first broadcast appearance since Dane’s death.
Gayheart said Dane went into the hospital for what the family expected to be another routine stay. “I said, ‘Listen, I’ll be back. I have a dinner. I’m going to this event.’ I had no idea that that was it, that that week was going to be our last week,” she told Shriver. “And nor did my daughters.”
She said that around the third day in the hospital, she noticed a change in how the doctors spoke to the family, and that Dane knew he was dying. During that final week, Gayheart and their daughters spent nights in his hospital room and played his favourite music. You can read AARP’s account of Gayheart’s interview for the full details of what she shared.
Gayheart told Shriver that after his diagnosis, Dane came to value life more, and that he found relief from lifelong mental anguish in his final year. She said she hopes readers of the memoir will understand Dane as more than the handsome doctor they watched on television.
Why the memoir matters
Dane went public with his ALS diagnosis in April 2025, saying at the time that he had begun to notice symptoms around 18 months earlier. He kept working and kept writing, and the memoir is the result of that final year.
For fans, the book fills in the story behind the headlines: the long road to a diagnosis, the decision to write it all down, and the message he wanted to leave for his daughters. For anyone affected by ALS, it is also a rare first-person account of living with the disease, written by someone who knew exactly how little time he had left.
