Finding her

You have a limited say to what happens to you as you grow up through childhood to adult life. Sable was only eight when she realized that.
Her father had died.
She had no say in what happened after that.
Her mother had fallen into depression and became unfit to care for them.
No say in what happened after that .
They were taken into a foster home.
She had no say in that .
All she wanted was to stay with her sister but that was too much to ask as she was taken away as well.
She thought she had no say in that and let her go... but now she's realized she did have an opinion to raise and now she's going after her. Except she didn't think of how hard that would be and what struggles her sister had become part of into since they were kids.
