I've read all the other Reacher books, several times over. They are uniformly well-written, and well-plotted. This one is different. I couldn't even finish it. Reading became a chore, because of the tedious plot and the poor writing.
This book is written by a completely different author, about a completely different Reacher character, involved in a nonsensical plot that will bore you.
Avoid buying it, so that this author can get the hint, and stop writing. He's killed the old Jack Reacher.
