Joe Chayefski has got what he always wanted: a reputation as one of America's top neuroscientists, a beautiful wife and two perfect daughters. But when his lab is attacked by animal rights activists, Joe is forced to face the past and reconnect with the son he abandoned twenty years earlier. As he struggles to deal with the sudden collision of his two lives - and to save his eldest daughter from the clutches of an unscrupulous tech company - Joe has to reconsider his priorities and take drastic action to save those he loves. An ambitious page-turner of a novel, They Know Not What They Do is perfect for fans of Jonathan Franzen and Dave Eggers.
