This is book 2 of the "Jack Reacher" series.

This note contains spoilers for the book.

Jack is in the wrong place at the wrong time again. These books seem to concentrate on coincidences as the basic cause of plot, perhaps in reaction to all the detectives who don't believe in them.

A woman who happens to be an FBI agent is kidnapped because she is the daughter of the Chairman of the Joint Chiefs and the god-daughter of the president. A militia madman is going to use her to as a human shield to protect their redoubt from the UN troops after they declare independence. Reacher happens to be walking by the door to the dry-cleaner as she comes out and they snatch her; so they snatch him too.

We see more people other than Reacher doing detective work this time, but we still have layers of ideas and evolving theories as early theories are disproven. Reacher is still completely immune to worry (he suppresses fear as needed, but he really doesn't worry much), and his idea of stability is staying a week in one place (mostly because he's handcuffed to things).

They even figure out in time that the dynamite that isn't where it was supposed to be (in the walls of the room housing the hostage, to discourage gunfire in that direction) has been hauled off as part of a car bomb and that the target is the San Francisco Federal Reserve bank.
