The Jack Reacher novels were created and originally written by British author Lee Child , the pen name of James Dover Grant.

In recent years, newer Jack Reacher books have been co‑written and then continued by his younger brother Andrew Grant, who publishes under the name Andrew Child.

Who wrote “Reacher”?

  • The character Jack Reacher and the long‑running book series were created by Lee Child in the 1990s, starting with the novel Killing Floor in 1997.
  • The TV series Reacher on Prime Video is based on these Jack Reacher novels by Lee Child.

What’s happening with Reacher now?

  • As Lee Child stepped back from writing, he passed the series to his brother Andrew Grant, now writing as Andrew Child, who continues new Jack Reacher books.
  • The franchise remains active, with recent novels (such as the 29th book discussed at the 2024 Portland Book Festival) and ongoing seasons of the Reacher TV adaptation.

In short: Lee Child created and wrote Reacher, and Andrew Child now carries the series forward.
