Roisin O'Mara. Rosi regrets a lot of things. She regrets having just scoffed the out-of-date chocolate bar she found down the bottom of her bag, and the cheese she ate before bed the night before-it gave her the strangest dreams. Her mammy always told her not to eat cheese before bed. She should have listened. Just like she should have listened when she asked her if she was sure doing the right thing getting married because that's her biggest regret of all.

When Rosi discovers a secret her husband's been keeping, she hightails it back to the family fold in Dublin. It's not just about her though, there's their son Noah to think about too, and Rosi's not sure she's strong enough to stand on her own two feet.

Reggie Nolan has regrets too. Saying sorry isn't in his vocabulary but time's 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 her 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?
