The story
Her son from the future says she has one year to start dating.
Emma is a single attorney, and one day a stranger stops her at her own front door and tells her he's her son, come back from the future. His warning makes no sense. Either she starts dating, or exactly a year from now she dies in a car crash. Emma digs into it to find out what's really going on, and what she finds is far darker. It was never Emma who was going to die.
