Reacher takes a stroll through a small Wisconsin town and sees a class ring in a pawn shop window: West Point 2005. The ring is tiny, for a woman, and it has her initials engraved on the inside. Reacher wonders what unlucky circumstance made her give up something she earned over four hard years. He decides to find out. And find the woman. And return her ring. So begins a harrowing journey that takes Reacher through the upper Midwest, from a lowlife bar on the sad side of a small town to a dirt-blown crossroads in the middle of nowhere, encountering bikers, cops, crooks, muscle, and a missing persons PI who wears a suit and a tie in the Wyoming wilderness. The deeper Reacher digs, and the more he learns, the more dangerous the terrain becomes.
