Ellie McCoy has a wonderful life. She is married to star journalist Joe, a man she adores. She has a great job in the financial industry, three marvellous children, and a nice house in Clontarf, close to Dublin bay. But tragedy is about to strike ... Ellie has always believed that important things happen to her in threes: her three siblings, her three boyfriends, her three children, and her three best friends, Caroline, Fiona and Mags. So when she arrives home one evening to be told that her husband Joe has died suddenly at a hotel in London, she is devastated. When she then finds out that he had been having an affair, she feels as though she may never pick up the pieces of her broken life.
