The book series dates back to 1998's "Lonesome Cowboy" and tells the story of siblings Savanah, Grady and Richard Weston as they cope with the death of their parents, keep the family ranch afloat and maneuver their own personal lives.
"Heart of Texas is an exciting project for me to be involved in as I very much relate to the dynamics and the powerful connection of friends and family of a small-town community," Twain said in a statement. "It's a story of love, laughter and true grit, all elements that so strongly influence my song writing."
Twain will be an executive producer for the series, teaming her with production company Reel World Management's Roma Roth and Christopher E. Perry, the duo behind Netflix's Virgin River TV series.
"Reel World Management is excited to collaborate with Shania Twain and Debbie Macomber, two outstanding female creatives who have successfully built powerhouse brands, to create a series that will resonate emotionally with a global audience while also reinforcing the valuable themes of tolerance, female empowerment, family, community, diversity and endurance," says Roth in a statement.
Twain's social media post teases new music from a five-time Grammy award winner and the queen of country pop.
"I'll be able to write about love and loss and hardship and triumph. It's going to run the gamut in that sense," Twain told The Hollywood Reporter. "I'm still getting a feel for the sound and mood of the music. I'll be getting together with an arranger, and that's going to be new for me as well, getting involved with the actual scoring."
Macomber's novels have spent over 1,000 weeks on the New York Times bestseller list.
