Chain Reaction by Lee Child, Andrew Child

The heart-pounding new Jack Reacher thriller from #1 New York Times bestselling authors Lee Child and Andrew Child.

Jack Reacher is hard to find. It's not easy to track him down. And he likes it that way. But General Susan Turner, based deep inside the Pentagon, has the means and the motive. She needs his help. A member of her team has been brutally murdered on covert duty. She can’t trust anyone she works with, not even her deputy. She needs someone from the outside. Someone who solves problems and disappears without a trace.

Reacher heads to Summertown, Colorado. A town as remote and bizarre as it gets. One diner, one motel, five massive data centers, two giant solar farms humming away in the dust. Total population: four people. And one of them is watching him. But Reacher isn’t built to run. He’s built to finish things. General Turner knows that if they come for Reacher, they’ll regret it—all the way to the top of the chain.
