What happens when you have nothing? You go looking for some thing, anything. For Adeline Sloane Sheppard, that was med school. By fourteen she found herself alone and navigating the dangers of a surgical internship until someone stepped in, the first family she ever had, Dr. Owen Hunt.
Two tours of duty, a failed marriage and a baby with a one night stand later, questioning her own mortality, Addy finds her way back to the closest thing she'd known to a home, her big brother. Her father had ties to the hospital he worked at, one way or another she could get answers. Her father was dead, or he'd be standing there across from surgery, but at least then she'd know.
Fate has a funny thing about timing though, after a fibril seizure and a paranoid doctor for a mother, Addy stops at a small suburban hospital with her daughter, only to meet her ex girlfriend, and an ambulance full of trauma patients with no attending to be found.
As soon as she thinks she's in the clear, they bring in one last trauma, and she finds her own eyes staring back at her.
