During the blizzard of 1978, a woman is discovered face down at the edge of her Delaware estate, a boxer, half-dead, by her side. Nearby, a CIA officer lies buried under two feet of snow. Their secret meeting—sabotaged. When Emma Quinn gets a call in her Manhattan apartment—your grandmother, found dead—she has no reason to suspect foul play. But she is drawn into a harrowing intrigue that harks back to the beginnings of the Cold War—and forced to confront the truth about her family and history as we know it.
