In Tripwire, Child pits ex-military policeman Jack Reacher against his most deadly and merciless adversary yet. Kirkus Reviews noted that "Reacher swashbuckles with the best of them" and Booklist called Tripwire "edgy, exciting reading."

Jack Reacher washes up in the Florida Keys with his savings running out; he spends his days digging pools and his nights as the bouncer in the local strip club. But a private investigator intrudes upon his tropical refuge, seeking Reacher out. When he discovers the PI's lifeless beaten body lying in the street, Reacher heads north to determine who is trying to find him and why.

Tracing the dead man's trail to New York, Reacher discovers the PI was working for Reacher's former commanding officer, mentor and close friend Leon Garber. Reacher teams up with Garber's daughter Jodie, a sharp Wall Street lawyer, to find out why Leon needed Reacher's help and they find themselves embroiled in a life-threatening search for the truth - and the deeper they dig, the more dangerous and twisted their path becomes.

In this third novel featuring Jack Reacher, author Lee Child masterfully intertwines the domains of the underworld and the bureaucracy of the U.S. Army. Reacher and Jodie uncover 30 years of deceit - and their love for each other - in a thriller that reaches its heart-stopping, plot twisting climax on the 88th floor of the World Trade Center.
