Sandra Lynn Cox Brown is a renowned American author known for her bestselling romantic and thriller suspense novels. She was born on March 12, 1948, in Waco, Texas, and raised in Ft. Worth. As the oldest of five daughters, Sandra was a responsible and mature girl who preferred reading books over playing with dolls. Her responsible nature continued as she graduated from Texas Christian University with a degree in English. She worked as a contributing feature reporter at the nationally syndicated PM Magazine in Dallas until the show experienced mass layoffs.

Sandra married Michael Brown, a former television anchorman and award-winning documentarian, and they have two children, Rachel and Ryan. Encouraged by her husband, Sandra ventured into fiction writing while their children were at school. Within a year, she sold her first novel, "Love's Encore," under the name Rachel Ryan (derived from the names of her children). She also wrote under the pseudonyms Laura Jordan and Erin St. Claire for Harlequin.

Since the publication of her first novel in 1981, Sandra has penned well over seventy novels, with her books appearing on the prestigious New York Times bestseller list over thirty times since 1990. In 1992, her novel "French Silk" was adapted into an ABC-TV movie.
