Lee Child and Andrew Child’s Chain Reaction is the thirty-first Jack Reacher novel, with a UK publication date of October 20. General Susan Turner calls Reacher into an investigation involving a murdered member of a covert team.

The publisher’s synopsis sends him to Summertown, Colorado, a place whose huge data centers sit alongside a tiny resident population. Turner needs an investigator outside the organization because she no longer knows which colleagues she can trust. The setup continues the series’ mobile, independent protagonist while placing the immediate mystery in an unusual modern landscape. Publication details and available editions are linked through the official publisher page.
