Five estranged cousins are lost in a maze of their family’s tangled secrets. Their grandparents, former potato farmers Gottfried and Marla Hemmings, managed to trade digging spuds for developing subdivisions and now they sit atop a million-dollar bank account—wealth they’ve refused to pass on to their adult children or their five teenage grandchildren. “Because we want them to thrive,” Marla always says. But for the Hemmings cousins, “thriving” feels a lot like slowly dying of a poison they started taking the moment they were born. As the rot beneath the surface of the Hemmings’ white suburban respectability destroys the family from within, the cousins find their ways back to one another, just in time to uncover the terrible cost of maintaining the family name.
