DavidSears grew up in the shadow of his brilliant younger 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, when Jason drowns, Diana will not accept the authorities conclusion that his death was accidental. Or perhaps Diana is going mad. She begins to send David faxes and e-mails about ancient murders, driven by her growing belief that the earth is Gaia, a living witness to her son's murder who could give evidence in the case she is building against her husband. David soon fears for his own family's safety as the seductive qualities of Diana's manic energy become impossible to ignore.
In "The Cloud of Unknowing, "Cook explores the power of blood and family mythology.

Praise For The Cloud of Unknowing


"Red Leaves is both heart-wrenching and gut-wrenching. A family can be 'briefly held,' and yet so enduring."--New York Daily News

"One of the most suspenseful of crime-fiction writers, [Cook] is also one of the most lyrical . . . Readers will glimpse blurred snapshots from their own lives--and be afraid."--The Plain Dealer (Cleveland)

"[Diana’s] inexorable descent into mania, narrated by her brother Dave, is as gripping as the mystery itself. A-"

"An eerie, unsettling, beautifully composed and suspenseful novel quite unlike anything Thomas H. Cook has written before."

"Cook smartly goes against genre expectations . . . What’s at stake isn’t so much the resolution of a mystery as the integrity of a family."
