Good Harbor.
(Book)

The seaside town of Gloucester, on Cape Ann, Massachusetts, is a place where the smell of the ocean lingers in the air. Fifty-nine-year-old Kathleen Levine, a longtime resident, is graceful, maternal, and steady, a devoted children's librarian, convert to Judaism, the mother of two grown sons. But when she is diagnosed with breast cancer--which killed her sister fifteen years earlier--her life is thrown into turmoil.
