She regrets having just snaffled the out of date Jacobs Club bar she found down the back of the cupboard, and the cheese she ate before bed the night before-it gave her the strangest dreams. Mammy always told her not to eat cheese before bed. She should have listened. Just like when Mammy asked her if she was sure doing the right thing getting married because that's her biggest regret of all. When Roisin discovers a secret her husband's been keeping from her she and their five year old son, Noah leave London and head for her old home in Dublin, O'Mara's Guesthouse on the Green. Reggie Nolan has regrets too. To say he's sorry, isn't in his vocabulary but time is running out. He's come to stay at O'Mara's to try and find the strength to put things right with the person he loves most in the world. With a little sisterly love and some advice from Mammy will Roisin be able to move forward? And can Reggie make amends for what he did thirty years ago, before it's too late?
