Ella Stuart has worked hard to achieve the perfect work-life balance: a high-flying career as a pediatric doctor, a charming husband, charity fundraiser Jackson Garrettand in urbane PR consultant William Ashfield, a passionate, worldly lover.

When tragedy strikes out of the blue, Ella's carefully ordered life is abruptly derailed.
