Left behind by her brother Noah, Nora is pushed into the path of Ethan, a dying stranger. Taking her in, he becomes the one person who can understand her pain, and together they heal in ways neither expected—she gives him a heart, while he gives her a reason to live. But after the transplant fails, Ethan is gone. Nora keeps their promise in Norway, comes back alone, rejects Noah's apology, and learns to stand on her own.
