The late, legendary country singer George Jones is known for his voice — twangy, but rich and agile — but another is chiming in on September 12. It belongs to Nancy Jones, his wife of 30 years until his death in 2013.

Mrs. Jones will release her memoir, Playin' Possum: My Memories of George Jones, on the Texan country singer's birthday this year. Although Nancy was George's fourth wife, their marriage lasted the longest.

She was aided by Ken Abraham, a writer and former professional musician who also had a hand in memoirs by famous astronaut Buzz Aldrin and actor Chuck Norris.

A release gives Mrs. Jones a lot of credit in the art of her husband's life, calling her "a strong, feisty woman who not only saved his life from cocaine addiction, alcoholism, and other abusive and self-destructive behaviors, but also was instrumental in saving his soul." But it certainly seems plausible from the length of the relationship, and perhaps more so from her reputation.

Nancy was George's manager, a semi-common but very challenging arrangement across genres in the music industry; These business-smart partners take on a lot protecting their loved ones from an industry that is notorious for being at odds with its creative drivers. The release touches on the "legends, half-truths, and downright lies" she had to endure about her partner.

The supportive Mrs. Jones also had a maternal relationship with Lisa Marie Presley, Elvis' daughter, and recently donated more than $80,000 for a fallen Alabama police officer and his injured counterpart.

The book promises both highs and lows in the life of the "hilarious" and "horrendous" Mr. Jones, and does not seem to turn away from the hardship that could have deterred Mrs. Jones from ever wanting to tell the story. It sets up a narrative from the promising early days of the relationship, through the regression to the same old problems, and finally to the other side.

Mrs. Jones discusses substance and interpersonal abuse, as well as "his battles with himself, and most of all, his battles against the demons that sought to control him and ultimately destroy him."

"Nancy knew there was a good man inside George Jones," the description asserts, "and she felt strongly that God had given her the assignment to help him, even if he hurt her."

Overall, the memoir seems to land on a peaceful note, celebrating the couple's success and the joy George Jone's music continues to bring to fans.

Playin' Possum: My Memories of George Jones is available for presale ($29) at georgejonesofficial.com. The book will be released on Tuesday, September 12.
