Impossible Promise — Jeanie P. Johnson

When Harmony's sister was put in a home for troubled girls because she became pregnant out of wedlock, Harmony applied for a job at the place because of rumors of underhanded happing's at the institution. She feared for her sister's safety and the life of her new baby once it was born. However, even though she promised to help her sister, it seemed like an impossible promise to keep. It became even more impossible when she was determined to take her sister's child under her own wing and leave her family forever to shelter it, in order to protect them from the shame of admitting to the illegitimate child's existence. Harmony finds herself in a small Kansas town where a Kickapoo Indian named Tayen, befriends her and offers to help her build a house. Now, she is faced with another impossible promise she made to herself, and that was not to fall in love with the intriguing young Indian she is irresistibly drawn to.
