"Stay away from his kind." Those were the words Priscilla Astor's father always taught her. As the pastor's daughter, seventeen-year-old Cillia is expected to follow the rules, look after her younger brother, and fit in with her settler friends.

Caught between her strict family, her true friendship with an Osage girl named Niabi, and a love her community forbids, Cillia must choose between expectations and her heart.
