The Shattered Line

What do you do when a stranger gives up their life for you... and haunts you every single night?
When a young girl has a brush with death, a mystery boy comes to her rescue, trading places with her ill-fated destiny. A few years down the line, she believes she has left the past behind as she's wrapped up in the embrace of her dream man, who sweeps her right off her feet.
But behind the façade, gruesome images of the boy lying in a pool of blood keep taunting her in her dreams.
The unsettling question lingers:  did the young boy survive, or did his life get cut short that night?
What would she tell him if she saw him again?
