This chilling legal thriller that brings readers into the depths of human memory "hooks you . . . right through to the last page" (Michael Connelly, New York Times–bestselling author of The Black Box). For generations the Underhill family has dominated Pennsylvania politics. Now, with their youngest son locked in a tight gubernatorial race, a simple accident threatens to derail the entire campaign. Floss Underhill, the family's elderly matriarch, has been discovered alive after falling from a gazebo into a ravine, and Brenna Kennedy gets brought in as a defense attorney for the family. The police don't think her fall was an accident—and soon neither does Kennedy. Kennedy's partner, psychologist and memory expert Jim Christensen, has been studying Floss Underhill for months in a group of Alzheimer's patients. Her mind ravaged by the disease, her body broken by the fall, Floss Underhill nevertheless knows something, and is trying to tell Christensen a family secret so explosive it could bring down an empire. But to bring the truth out, Kennedy and Christensen will have to face some powerful enemies in this twisting mystery-thriller from an author who "may well become a thriller force to be reckoned with" (James Ellroy, New York Times–bestselling author of L.A. Confidential).
