This story was created February 11th 2017
Mandi is the owner of an adoption center.
Mandi found a small child around 3 years old while she was walking the woods in the middle of July. You could tell she had been in the woods for a few days. She knew nothing about herself not even her name. Mandi named her Cara.
She brought Cara to her adoption center and raised her, just like she would any young child. Mandi became attached to Cara and treated her a bit better than the other kids and teenagers. It's been 13 years since the day she was found. On her 15th birthday, something happened. Now Cara has a secret that only Mandi knows and doesn't plan on letting anyone find out. Cara knows nothing about who she truly is and why she is like this..what happens when someone wants to adopt her? Will she tell them? Will they find out?
