Her heart. It beats in her chest. Quickens and then ceases to as she succumbs to the paralysis beneath her closed eyelids.
Broken, Sophie is believed to be beyond repair. Sometimes bad things happen to good people, and we are powerless to stop them; cursed with hindsight to plague us with thoughts of what could have been.
Life, at the moment, seems to be an everlasting nightmare for her, all the light in her life being sucked away. That is, until, in the darkest of hours, Roah stumbles across Sophie with the promise of being able to fix her and bring back a glimmer of light to her life.
There's no denying the electrifying spark between them. They're the perfect match, though Sophie isn't willing to admit it. So, Roah does the most romantic thing a man can do, in the most unromantic way possible.
