Chain Reaction: A Reacher Novel

Set in Washington, DC, the novel begins with General Susan Turner seeking help from Jack Reacher, a wanderer whose trail is difficult to follow. Reacher receives an invitation to meet with her, though the agency behind it remains unnamed. That uncertain summons supplies the story’s central setup: a familiar figure is drawn toward a meeting whose purpose is not fully disclosed. Presented as a thriller, the book frames its intrigue around the request, the search for Reacher, and the unanswered questions surrounding the invitation.
