The Friday Harbour series of women's fiction novels is set in San Juan Island just off of the Washington State Coast - romantic and varied, with rocky shores, sandy beaches, rich woodlands and pasture land - and the prosperous Friday Harbour area.

The series is centered around the Nolan family, consisting of two brothers and a sister, the owners of an island vineyard and restaurant. The Nolans' mother Jessica has just passed away, and a mysterious stranger attends the funeral. He reveals that he is an illegitimate child Jessica had given birth to, and given up for adoption, before she married. This family secret leads to many new questions and challenges, which test the bonds of love and loyalty, and ultimately show the Nolans what family is all about.
