I just read the new Reacher book In Too Deep. It's solid, but something is lacking a little bit.
It is a promising premise. Reacher wakes up, handcuffed to a steel table, concussed, and with a broken arm. He has no idea how he got there, he only knows he's going to make them regret what they've done to him. That sits the table for an interesting novel which focuses on Reacher's brain, rather than his brawn. Without giving too much away, the co-authors give up on that intriguing premise far too quickly.
In the inevitable physical confrontations, even a concussed, one armed Jack Reacher is more than a match for every other character. That ends up taking the drama and interest out of the physical confrontations in the long run.
Overall, this was still an interesting read, but I feel as if the Reacher series is becoming more one-dimensional with Reacher, essentially becoming a superhero.
