The heart is exquisite. You'll never hear anyone wax poetic over an organ quite like they do the heart. When you're lost in the world? Follow your heart. When your love for someone is unwavering, unparalleled and unprecedented? You give them your heart. As a lead pediatric cardiac surgeon, I knew better than anyone that the heart is equally as powerful as it is delicate. The heart giveth just as easily as it taketh away. And until the day Kelly Potter darkened my doorway that was all just part of the job.She rolled in like a slow evening storm, fierce and beautiful, fighting for the life of her unborn child. It should have been business as usual. I was a doctor. Her child the patient. But Kelly was more. She was the one who got away.I wouldn't make the same mistake twice.It didn't matter what the rules were.For once, I was listening to my heart.
