What could drive a mother to do the unthinkable? Before: Emma Cormac married into a perfect life but now she's barely coping. Inside a brand new, palatial home, her three young children need more than she can give. Clem, a wilful four year old, is intent on mimicking her grandmother; the formidable matriarch Pat Cormac. Arthur is almost three and still won't speak. At least baby Robbie is perfect. He's the future of the family. So why can't Emma hold him without wanting to scream? Beyond their gleaming windows, a lake vista is evaporating. The birds have mostly disappeared, too. All over Shorehaven, the Cormac family buys up land to develop into cheap housing for people they openly scorn. After: The summers have grown even fiercer and the Cormac name doesn't mean what it used to. Arthur has taken it abroad, far from a family unable to understand him. Clem is a young artist who turns obsessively to the same dark subject. Pat doesn't even know what legacy means now. Not since the ground started sinking beneath her.
