Mom's Regret & Love? I Refuse!

Zoe Lynn was taken from her family as a small child and raised by a woman she called grandmother. As an adult she was diagnosed with stomach cancer. Around the same time the grandmother needed an operation, and Zoe donated a kidney to the daughter of the richest family. The payment covered the operation. The recipient's mother was Zoe's birth mother. The girl who received the kidney had been raised in the family in Zoe's place. When the connection came out, the mother and Zoe's older brother offered her a position in the household as a foster daughter and nothing beyond that. Zoe was left in a bad state. Daisy Grey found her and took her in. Zoe changed her name and took Daisy's surname. She trained as a scientist, developed a cancer drug, and became known in her field. Later her birth mother and brother came to her to say they had been wrong.
