Misty survived a horrible life and terrible parents and siblings to make it across the stars when her world ended. Those that hurt her were on the same ship. Family groups needed to be kept together, and she accepted that her suffering wasn't going to end.
Four and a half years of a menial job later, she meets a few people that are genuinely kind, and she enjoys the kindness while it lasts. A few days later, she is kidnapped and held for ransom, and no one will pay.
She is ready to be auctioned off to the highest bidder when a rescuer appears, and it is the person who offered her kindness at the café. Now, he is offering a contract, and she doesn't have another option. She will sign a contract with the overseer and see how long she lasts.
