Striking Freedom by Viola Grace

Lacey was the newest member of the station before the explosion, but she lost her future right after the blast.
Lacey had grown up with privilege, but she learned early exactly how deals got made. She used to use her skills to get Adaptation Station their hard-to-come-by supplies, but after the blast, the family that she had been gaining was pulled from her.
Lacey was transported across the stars where she sat at the side of her grandfather while he bargained away the human race. When she objected, she became a test subject that the Splice took apart.
Wallowing in depression lasted for a while, but when she got back on her feet and stood tall, she realized that she had work to do, and no one was going to do it for her. Time to get a plan into position and get her band back together.
