Some rules are made to protect the heart... until love breaks every single one. Isabella Carter never planned to fall in love. She has one rule: never let anyone get too close. Adrian Knight is charming, confident, and completely impossible to ignore. He has his own rules-and none of them include falling for a girl who keeps pushing him away. But as secrets, jealousy, friendship, heartbreak, and unexpected feelings begin to change everything, they realize that the heart has only one rule... Because when love is real... there are no rules. A slow-burn romance filled with unforgettable moments, emotional twists, laughter, heartbreak, and a love worth fighting for.
