An experienced clinical psychologist, Helen Myrer has been immersed in the study of society's most troubled minds. She decides to leave her high-pressure world for rest and rejuvenation at the isolated cabin her late husband called the Old Secret, a place where she once shared the magic of a wonderful marriage. But once she walks into the little house in the New Hampshire woods, with Lake Glory glinting down below, she will find no rest. Instead, this woman of intelligence, strength, and success is about to enter a labyrinth of the most terrifying order - a maze of human depravity that will take her to the farthest reaches of her own courage and will to survive.
