Sarah Houston Hawks, a young girl, a lone survivor on the trail west. She is found by Tall Feather. He is the fierce, intelligent medicine man for the people. He brings her home and makes Sarah his own daughter. She becomes Aponi. The problem is that her remaining rich and powerful family back east wants her returned... at all costs.

Why? Eugenics. Her mother was planned for, but she was not. Sarah was a love child, not a desired union. Yet, later it is found that she carries all the qualities the Hawks have worked toward for years.

What is Eugenics? That is a set of beliefs and practices that aim to improve the genetic quality of the human population. The Hawks' family and the Andrews' family had practiced birth manipulation time and again. The search for perfection was ever close, but out of reach. Then came Sarah.
