Gary Sinise’s new book, Graceful Warrior: The True Story of a Son, a Father, and a Family Who Carried Each Other Through, will be available on Nov. 10.

The story chronicles the beauty of his son, Mac’s, life and how his family handled the grief following his death.

“This project has been two years in the making and it is more deeply personal than anything I have ever done,” Sinise said in a social media post. “I wrote this book not only to honor my son, but also to offer hope, strength and comfort to others who are currently walking through their own challenging valleys.”

He shared a glimpse of what readers will learn about Mac in the book. He was a brilliant composer who loved his family.

“At 27, he was diagnosed with chordoma, a rare form of bone cancer,” Sinise said. “Mac never let this slow him down. He pushed forward, serving through the Gary Sinise Foundation until he needed to step back to focus on the fight.”

Despite the dark news, Mac lived his life to the fullest and gave his time to helping others, writing and recording music.

Sinise is eager to share about Mac, someone who was so close to his heart.

“I look forward to sharing more about Mac, my family’s journey, and the love and faith that carried us through in the coming weeks. And my heart goes out to anyone struggling with a similar challenge. If you’d like to pre-order the book, you can do so through Barnes & Nobles, Amazon or Premier Collectibles,” he added.

Sinise often talks about Mac and sometimes performs songs he wrote with his Lt. Dan Band when he plays for troops.

Much of Mac’s music has been published posthumously. After he died in 2024, Sinise found music and letters that Mac had written to his family on his digital devices. Sinise believes he left these intentionally for them to find.

There were also “videos he’d made and kept for us to see should anything happen. Beautiful things that he meant for us to have.”

Sinise said of one of his melodies, “Angel’s Theme,” “It was stored in his files from his early college days. Mac was just beginning to write on piano and for other instruments and came up with the beautiful melody featuring violin and piano. Not only did I find the recording he made, but I also found his original chart and arrangement.”

Sinise loved it so much that he made sure to include it in his band’s set list. It was one of the first songs that Mac ever composed.

Sinise said in a clip of the song, “I hope you take a moment to view. Miss you, Mac.”

Sinise’s new book is a thoughtful reflection and celebration of Mac’s life. It’s beautiful that he is honored in this way.
