Rachel's Secret (Riverhaven Years #1)
B.J. Hoff

When the wounded Irish American riverboat captain, Jeremiah Gant, bursts into the rural Amish setting of Riverhaven, he brings chaos and conflict to the community--especially for young widow, Rachel Brenneman. The unwelcome "outsider" needs a safe place to recuperate before continuing his secret role as an Underground Railroad conductor. Neither he nor Rachel is prepared for the forbidden love that threatens to endanger a man's mission, a woman's heart, and a way of life for an entire people.
