Isadora Matilde Valverde is 20, hot, reckless - and completely uninterested in football. One night in a Madrid club, she meets Trent Alexander-Arnold, 27, new at Real Madrid. He tells himself she's too young. Too dangerous. A distraction he doesn't need. She pulls him in anyway. They don't exchange last names. They don't ask questions. One intense night - and by morning, she's gone. Weeks later, after a match at the Santiago Bernabéu, Trent sees her again - running straight into the arms of his teammate Federico Valverde. His teammate. Her older brother. Neither of them knew. What starts as a reckless mistake turns into a secret they can't seem to end. And when an older brother finds out that his teammate is sleeping with his little sister... ...everything explodes.
