Jack Reacher has no place to go, and all the time in the world to get there. A remote railroad stop on the prairie with the curious name of Mother's Rest seems perfect for an aimless one-day stopover. He expects to find a lonely pioneer tombstone in a sea of nearly-ripe wheat.

Instead there is a woman waiting for a missing colleague, a cryptic note about two hundred deaths, and a small town full of silent, watchful people. Reacher's one-day stopover turns into an open-ended quest leading to the most hidden reaches of the internet, and right into the nightmare heart of darkness.
