This is the third book I've read by this author in her apparently sanctioned (by Lee Child) "looking for Jack Reacher" series of books. The FBI agent characters, Otto and Gaspar, are beginning to round out as we learn more of their history and their lives. Both characters, especially Otto, have some pointy bits but are basically worthwhile people to spend time with.
However, I'm getting a bit weary of the secretive, untouchable Powers That Be who jerk the agents around in some kind of behind-the-scenes competition to 1) find Jack Reacher; 2) kill Jack Reacher; or 3) some of each. I find it unlikely that actual FBI agents would willingly accept being thrashed all around the county/world nearly at random, with so little idea of what their superiors actually want with the target. Are agents really so afraid of being terminated at any moment without cause?
I suppose a great deal of these books are to do with the repercussions that Jack Reacher's high, wide and handsome style leaves behind in the lives of those he encounters. After all, many if not most of the Reacher books follow the "boy comes to town, boy gets hassled or discovers nefarious activity, boy meets intriguing woman, boy gets laid, boy decimates the bad guys and changes the entire dynamic of town without regard to consequences, boy hitchhikes on his way." So an exploration of the actual aftereffects is interesting, except that 20 years later, just *coincidentally* more people die, more crimes are uncovered, and the FBI agents are there to witness it, sometimes participate, and then they too, leave without regard to what they've wrought.
I'm starting to get a "Finding Bigfoot" vibe here. In order for this series to continue to work, Jack Reacher must not be found. He can lurk, and *maybe* be spotted in the shadows, but must never be found. However the writing style is smooth, quite readable, and other than the quibbles about FBI behavior, generally believable. I will probably pick up the next book in the series, but not right away.
