Mace is your typical stay-at-home mom of twin boys. It wasn't supposed to be this way. Not for this long, but it was Sammy's decision. She's been with him for nearly a decade. They were high school sweethearts that had a chance meeting rivaling that of a young adult rom-com. He was a shy, sweet boy and she was a bright, friendly girl. Everything changed on her 18th birthday with the sudden death of her parents. But Sammy was there for her through all of it.
Years later, the boys are nearly 8 years old when she starts letting her mind wander more and more. Thinking about past moments with her mom and dad, the girl she used to be compared to now, and how nothing is ever as she imagined. She realizes that Sammy has been trying to control nearly everything about her and the boys' lives. Not only that, but he's abusive and becoming worse. She needs to find a way out.
Her best friend from work, Ash, has been begging her since day one to come back to work at the factory she left when she was pregnant. She agrees as she sees that as her only way to take the first step to freedom. This begins a chain of events involving a dusty gift box containing a strange key and note that will change all of their lives. Forever.
