The Cloud of Unknowing/Thomas H. Cook

Description David Sears grew up in the shadow of his brilliant sister, Diana, convinced by their father that she would accomplish great things. Instead, she married and had a son, Jason, who--like David and Diana's father--is schizophrenic. Her husband, Mark, a geneticist, never made peace with Jason's condition. Perhaps this is why Diana will not accept the authorities' conclusion that Jason's drowning death was accidental. Or perhaps Diana is going mad. As she builds a case against her husband and the seductive qualities of her manic energy become impossible to ignore, David finds himself afraid for his own family's safety. In The Cloud of Unknowing, Cook explores the power of blood and family mythology. About the Author Thomas H. Cook is the author of nineteen novels and two works of nonfiction.
