When Lee Child announced his retirement after the 25th novel in the Jack Reacher series, fans like me were disappointed.
The 26th book is The Sentinel (2020) co-authored by James Grant and his younger brother Andrew Grant but published using their respective pen names of Lee Child and Andrew Child.
Sounds like the much younger brother did most of the writing.
He’s taking over the franchise.
Happily, Sentinel is excellent.
In this one, Reacher battles those behind a ransomware cyber attack in a small town a couple of hours out of Nashville.
