In a world where soulmates are bound to each other with a single red string from the age of 16 and onward, Amber Abott, an MMA fighter and high school student, uses fate as a weapon against time in hopes of salvaging her crumbling relationship with her once-childhood-friend, Seth Kohren, a boxer who attends the same school as her. The two were best friends since birth, until a random day in fifth grade, when he pushed her away from him. And had done so ever since. She became his shadow, not even a worthy rival in his eyes, despite the fact that she was the only person that could keep up with his abelites. He may be the top student, but she was the top fighter. But what happens when he can't push her away anymore? What happens when fate ties her to him on the day of her 16th birthday? Not only that, but the string is unbreakable. Nothing, not knives, not scissors, not even a chainsaw, can break through their unusual string. Is it the small, golden thread embedded into their string that nobody else has? Or could it be that...they're really just meant to be?
