For Kate Green, nothing was as important as the happiness and well-being of her two little boys, Reef and Finn, and her loving husband, St. John, known as "Singe". They had a wonderfully happy family life in Somerset, England. But then tragedy struck - Kate was diagnosed with breast cancer that couldn't be cured. During her last few days, Kate created what she called Mum's List. With Singe's help she wrote down her thoughts, dreams, and wishes, trying to help the man she loved create the best life for their sons after she was gone.
