To quote Wikipedia: "In January 2020, [Lee] Child announced that he would retire from writing the Jack Reacher series and hand it to his brother Andrew Grant, who would write further books of the series under the surname Child. He intended to write the next few books with Grant before passing the series entirely over to him."
Andrew Grant was already an established thriller writer, with nine novels published. The two brothers have collaborated on five Jack Reacher novels to date, and a sixth is scheduled for publication later this year.
