Her heart had always betrayed her. Madeline grew up knowing it could stop at any moment - not from love, not from grief, but from a flaw stitched into her since birth. She learned to smile through hospital rooms, to hide the pills in her bag, to pretend the tremor in her chest was nothing more than nerves. And then there was Lando. Bright, reckless, full of speed and sunlight. He lived like tomorrow wasn't promised - while Madeline lived every day fearing it might be her last. Their worlds were never meant to cross. But when they did, the crash was inevitable. And beautiful. And dangerous. Because some hearts are too fragile to hold. And some loves burn too brightly to survive.
