Thirty-something Lucy and Luke Harte, have everything - jobs they love, a great home, lovely family and friends - except the one thing they want the most: a baby. After eight miscarriages and years of disappointment, their luck has finally turned. Lucy is nearly four months pregnant - the furthest she has ever got - and both she and Luke are ecstatic. But fate has another plan for Lucy and, on the day of their fifth wedding anniversary, Luke is involved in a horrific car accident. As Luke lies in a coma, Lucy tries, with the support of her mother-in-law Patricia, best friend Dee and sister-in-law Nell, to hold everything together. But life for Lucy and the Harte family is about to change more than they could ever have imagined when Stella, a colleague of Luke's, turns up at the hospital pregnant with his baby.
