Romance Novel with multiple acts first focusing on a daughter and second on her mother. I think one named Raymona? Daughter runs away and sleeps with a priest. Mother is a mistress.

This book was on a book that was on my High School Summer reading list in the late 2000's. Title has about all the details I can recall. I do not think it was the 1884 Helen Hunt Jackson novel, after reading the synopsis. Though possibly that is the book meant to be on the reading list.
