A bit disappointed with reading it and if I give it a rating I would give it a 4/10, a strange ending, and to me, I think he was trying to make the guy another Jack Reacher with a different personality and I could pick up little bits of a Lee Child in the book, so in all, he was trying to write the same as his brother but he got it all wrong.
Now I am reading the book below by an ex-actor now turned author, Gene Hackman and the book is not a bad read at all.
