Jack Reacher Book 31: Chain Reaction's Release Date Confirmed

Anyone typing "Jack Reacher new book release date" into a search bar this month gets a clear answer. Chain Reaction, the 31st full-length novel in the series, is confirmed for 20 October 2026 in both the UK and the US, as reported by ScreenRant and Collider.

That's the next outing for Jack Reacher, the drifting ex-military policeman who has carried Lee Child's series since Killing Floor in 1997. This time the writing credit belongs jointly to Lee Child and his brother Andrew Child, continuing a partnership that began with The Sentinel in 2020.

According to ScreenRant, the new book brings back General Susan Turner, a character readers last saw properly in Never Go Back, who turns to Reacher after a member of her team is murdered during a covert operation. The case pulls him towards a small Colorado community called Summertown, where, as Collider notes, the story follows "a murder, the Pentagon, and a remote Colorado town where something very clearly is not adding up."

It's a deliberate bit of continuity. ScreenRant points out that Susan Turner is one of the series' longest-running female characters, having previously featured across 61 Hours, Never Go Back, and been referenced in several books in between. Her return marks the first time Andrew Child has reached back into that older continuity rather than starting fresh.

The release lands only weeks after the fourth season of Amazon's Reacher television adaptation wrapped up. ScreenRant reported that the TV finale aired in mid-September, with the new novel arriving on the page barely a month later. The show and the books now run on parallel tracks: the series has so far adapted Killing Floor, Bad Luck And Trouble, Persuader and Gone Tomorrow, while the novels keep moving forward on their own separate timeline with Chain Reaction as book 31.

It's also a milestone for the writing handover. Andrew Child first joined his brother as co-author on The Sentinel and has since built up a run of titles alongside him, including Better Off Dead, No Plan B, The Secret, In Too Deep and last year's Exit Strategy, before Chain Reaction. The pairing has become the standard way new Reacher stories are produced, with both names remaining on the cover even as Andrew takes a larger hand in the writing itself.

Chain Reaction follows straight on from Exit Strategy (2025) as the 31st book we track from this writing partnership. Readers can see the full run of Lee Child's titles here and the books Andrew Child has co-written here, covering the catalogue from Killing Floor right through to this new release.

You can find Chain Reaction's dedicated page here, which carries the 20 October 2026 publication date and will update the moment the book is officially out.

For a series that has run for nearly thirty years with barely a gap between instalments, it's easy to lose track of exactly when the next one lands. That's the problem Bleepia solves: we send an email the day a book from an author you follow is actually published, so there's no need to keep checking shop shelves or publisher calendars.

If you want Chain Reaction to land in your inbox the day it's released, follow your authors and add Lee Child and Andrew Child to your list. It takes a minute to create a free account, and from then on you'll hear about new Reacher books, and anything else on your list, the day they go on sale rather than weeks after everyone else has already started reading.
