After a brief stop in New York City (Gone Tomorrow), Jack Reacher is back in his element?Smalltown, U.S.A.?in bestseller Child's fine 14th thriller to feature the roving ex-military cop. When a tour bus on which he bummed a ride skids off the road and crashes, Reacher finds himself in Bolton, S.Dak., a tiny burg with big problems. A highly sophisticated methamphetamine lab run by a vicious Mexican drug cartel has begun operating outside town at an abandoned military facility. After figuring out the snow-bound, marooned Reacher's smart, great with weapons, and capable of tapping military intelligence, the helpless local cops enlist his assistance, and, as always, he displays plenty of derring-do, mental acuity, and good old-fashioned decency. While the action is slower than usual, series fans will appreciate some new insights that Child provides into his hero's psyche and background as well as a cliffhanger ending.
