Racing Hearts K12

Sienna Wolff was never meant to fall in love with racing again. A prodigy turned engineer, she walked away from driving after heartbreak on the karting track shattered her trust - and her dreams. Now one of Mercedes' most brilliant minds, she's sworn off the fast-paced chaos of emotion in favor of data, strategy, and control.

Enter Kimi Antonelli: the newest Formula 1 rookie with the weight of the world - and Lewis Hamilton's legacy - on his shoulders. Fiercely talented, sharp-tongued, and unexpectedly vulnerable, Kimi is everything Sienna doesn't want to get involved with... and exactly the person who might break through the walls she's so carefully built.

What begins as a tense, professional partnership grows into an undeniable bond as Kimi teaches Sienna Italian during late-night sim runs and she grounds him through the pressure of the grid. But when sabotage, past secrets, and the ever-watching eye of the media threaten to pull them apart, both must decide what they're really racing toward - glory, redemption, or each other.

From rain-soaked paddocks to secret airport glances, quiet garage moments to forehead kisses after crashes, Racing Hearts is a story about trust, timing, and the quiet love that builds in the spaces between.
