Wait until I show you a picture of the boys,” beams Evelyn O’Rourke as we enjoy a cup of tea in the RTÉ canteen. She whips out the phone and photos of her young sons Oisín (five) and Ross (four) fill the screen. A big smile is plastered on Oisín’s adorable face as he plays on his scooter in the park. And then there is Ross, Evelyn’s youngest son, happy, healthy and full of life, the boy who is the focus of her bestselling book Dear Ross. “Wasn’t he totally worth it,” smiles Evelyn proudly.
