"In this novel, Jack Reacher is approached by a female Secret Service agent who needs a favor - and needs it yesterday. The head of a high-security detail, she wants Reacher to run a test to find the holes in her system. How else can she breathe easy, sure that her protection is truly effective? Reacher is the right man for the job - skilled, stealthy, and unknown. But the things she doesn't tell him could get them both killed. She knows that a group of desperate men have her Secret Service team - and their charge, the newly elected vice-president - in their sights. These men will stop at nothing to realize their objective. And they have planned well - but they haven't planned on Reacher. For only Reacher has the head and heart to corner his prey and bring them to justice - without fail."--BOOK JACKET.
