Twenty-five year old Billie Romano is struggling. She is grieving the death of her beloved dad and nothing in her life is going right. Her mother has remarried with indecent haste, so when her grandfather presents everyone in the family with a DNA testing kit for fun, Billie couldn't be less interested in playing happy families.

The test results are shocking, and Billie finds herself caught in a turmoil of emotions as she is faced with a reality she could never have imagined.

Her journey of discovery takes her to Ireland, and to the stunningly beautiful Castle Dysert on the Wild Atlantic Coast, when Conor O'Shea once more steps into the role of fixer of problems and soother of troubled souls. Can Billie make a whole new start or are some cans of worms best left closed?
