Grace has always been the responsible one. After losing her parents, responsibility was all she knew-taking care of her younger sister, keeping her head down, never letting herself slip. No parties, no distractions, and definitely no time for love. It never mattered anyway. Love was something that never seemed to belong to her. Until now. What started as a simple tango class, just a chance to learn something she'd always admired, changes everything the moment she meets her. The instructor. Beautiful, magnetic, impossible to look away from. But falling for her is dangerous. Because she's married. She's forbidden. And she's the mother of her sister's best friend. Grace promised herself she would never risk her heart. But on the dance floor, with every step and every stolen glance, she's beginning to wonder if some loves are worth breaking all the rules for.
