Late actor Eric Dane’s posthumous memoir, My Book of Days: A Memoir in Moments, offers an unfiltered look at his career, his intense private battles with substance addiction, and the devastating physical reality of amyotrophic lateral sclerosis (ALS). Published on November 3, 2026, by The Open Field, an imprint of Penguin Publishing Group, the book was written prior to Dane’s death in February 2026 at the age of 53 following a courageous fight against the neurodegenerative disease.
Excerpts published ahead of the release highlight the complex trajectory of Dane’s life, from his breakout years as Dr. Mark Sloan on ABC’s medical drama Grey’s Anatomy to his final months spent surrounded by family.
Early Symptoms and the ALS Diagnosis
In the memoir, Dane pinpoints January 7, 2024, as the exact moment he realized something was fundamentally wrong with his body. While eating sushi with his children, he noticed he could not properly maneuver chopsticks with his right hand due to numbness and tingling in his fingers. Initially dismissing it as a nerve issue from excessive texting, his symptoms worsened drastically over the following weeks.
Following nine months of medical examinations and neurological testing, Dr. Mark Terrelonge, associate program director of neurology residency at the University of California, San Francisco, diagnosed Dane with ALS in April 2025. Dane immediately pulled over in his car to call his then-estranged wife, actress Rebecca Gayheart.
“I say to Rebecca on the phone, ‘It’s what we feared.’ I don’t remember a single word I said after that. I remember only feeling a violent impact… and Rebecca wailing on the other end of the phone, and then I really lose it,” Dane wrote.
Although Gayheart and Dane had filed for divorce in 2018 after 14 years of marriage, they never finalized the paperwork, continuing to co-parent their daughters, Billie and Georgia. Upon hearing the diagnosis, Gayheart dismissed her petition for divorce and vowed to stand by him, telling him, “I’m here, we’ll fight this together, I’m not going anywhere.”
Substance Addiction Struggles During Grey’s Anatomy
Dane’s memoir also revisits the darker periods of his personal life, specifically detailing how painkiller addiction impacted his tenure on Grey’s Anatomy. After joining the hit series in 2005 during its second season, Dane suffered a severe painkiller relapse in 2008 following a cervical disc injury sustained while working out.
Describing the physical and mental toll, Dane wrote that his weight dropped to 170 pounds, noting that his appearance changed significantly. Despite establishing a strict personal rule never to arrive at work under the influence, he admitted to struggling immensely behind the scenes.
Show creator Shonda Rhimes frequently stepped in to support him, offering breaks and facilitating his entry into treatment centers during hiatuses. Dane entered rehabilitation five times throughout his run on the medical drama.
Addressing His Departure From Grey’s Anatomy
Reflecting on his departure from Grey’s Anatomy at the close of season 8 in 2012, Dane clarified the circumstances surrounding his character’s exit. While his addiction certainly complicated matters, he explained that the ultimate decision came down to financial considerations.
“My Grey’s Anatomy ending does come, but not because of my addiction, although it’s safe to say my addiction didn’t help. The reason comes down to money,” he wrote. “Despite Mark Sloan’s popularity, I have become too expensive. I have become expendable.”
Final Moments and Legacy With His Daughters
As the disease progressed, Dane focused heavily on his role as a father to daughters Billie and Georgia. In December 2025, an emotional moment occurred following Billie’s ballet performance of The Nutcracker. Due to his advanced muscle weakness, Dane was unable to lift his arms to embrace her in their traditional post-show hug.
Recalling the encounter, Dane described the profound emotional beauty of the shared tears and noted that the moment forged a new tradition between them. Throughout his battle, Dane remained an advocate for neurological disease research, collaborating with organizations like I AM ALS to campaign for increased federal funding and public awareness before his passing in February 2026.
