Seth Miller had been a part of the foster system since the age of 7. When he was 18, as a legal adult, he was no longer eligible for the system, and like many former foster children, faced homelessness. Then something amazing happened. Seth learned he had a younger, biological sister who was adopted as a baby and living in Rockwall. When his sister's family discovered Seth's situation, they not only invited Seth to live with them, but adopted him as well. More info at Yahoo Shine.
