Chain Reaction by Lee Child and Andrew Child (out 20 Oct 2026)

Jack Reacher, \"the coolest continuing series character\" (Stephen King), returns in a brand new, pulse-pounding read from Lee and Andrew Child. Jack Reacher is a hard man to track down. And that's just the way he likes it.But General Susan Turner, based deep inside the Pentagon, has the means, and the motive, to do so. 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 centres, 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: if they come for him, they'll regret it - all the way to the top of the chain.
