But the only thing she really wants – her heart’s desire – is the one thing she can never have. Her sister, the beautiful Susannah, has made a mess of her life. Like a reverse Midas, everything she touches turns sour. But fate puts Grace’s future in Susannah’s hands, changing the balance of power between the sisters forever.
