New York Times bestselling author Jeff Rovin has held readers in breathless suspense with his Tom Clancy's Op-Center novels. He has created compelling characters with vividly rendered emotions and actions. His page-turning thrillers have addressed questions of good and evil in our times. Now, Rovin confronts the question of Good and Evil on the ultimate battleground. A human soul hangs in the balance, and thousands of years of religious teachings depict only the beginning of the fight for dominion over man. Psychologist Sarah Lynch is stunned when one of her young patients hangs himself. Evidence reveals that Fredric had become a Satanist. Intending to solve the puzzle of Fredric's death, Sarah attempts to conjure the devil--surely then she will understand what the teenager was thinking. Sarah knows that belief in God and the Devil is a construct of the human mind and that people contain within them both good and evil. Her own family is the perfect example. Sarah's mother is still in denial about her dead husband's alcoholism, but acts as a wonderful grandparent to the son of the family's live-in housekeeper. Her alcoholic brother bounces from girlfriend to girlfriend and job to job, but always there when Sarah needs him. And Sarah herself? She lost her faith more than a decade ago, during a personal crisis. But she is dedicated to giving others the help she did not receive. Even the nun who is Sarah's best friend cannot break through Sarah's shield of cynicism. But Satan can. The Devil himself rises in Sarah's office, sometimes a being of dark smoke and sometimes a creature of all-too-perfect, seductive flesh. Most disturbing is Satan's claim that only by following him can peoplefind real happiness. In the Devil's theology, God is a brutal, jealous bully. And as God and Satan battle for Sarah's soul, Sarah comes to believe him. She forgets that he is the Master of Lies . . . .
