Danielle "Danny" Alvarez has always been the quiet one-the soft-spoken, "boring" friend who never makes waves in their small Indiana town. With her easygoing lifestyle and shy demeanor, everyone assumes Danielle is a sweet good girl who just needs to find a man to settle down with. But Danielle has a secret. Beneath the surface, she's a nymphomaniac, a woman who craves pleasure so intensely it consumes her every thought. She's just learned to hide it behind a polished smile and quiet charm... until Jackson Kingsley walks into her life. Jackson is everything Danielle never let herself dream about-tall, magnetic, successful, and so deliciously dangerous that he threatens to break down every wall she's built. What starts as innocent flirtation quickly spirals into a sexual awakening Danielle can't control. He teases, denies, devours, and pushes her further than she's ever gone before-mentally, physically, and emotionally. But Danielle's new addiction to Jackson's touch comes with risks. Because someone from her past-someone who once tasted her secret side-can't stand to see her unravel for another man. The Good Girl's Undoing is a sensual, explicit, and emotionally charged erotic novel that blends romantic tension, dominance, and the thrill of forbidden temptation. It's the story of a woman embracing the darkest parts of herself and the man determined to unchain every ounce of her desire... no matter the cost.
