Your heroine is a paramedic. She’s used to difficult situations, high stress, and ugly surprises. But nothing surprises her more than when she shows up to an emergency scene and finds her ex. A man, once the love of her life who she’s never really gotten over, and who is supposed to be dead.
What happens? Why is he hurt? How does he explain the fact that he’s alive and where has he been all this time? Why did he let her think he was dead? How does she react when she sees him?
