It's been a while since I've kept up with his stuff, honestly. Rosenberg's early work was this pulse-pounding action, but I feel like his last few novels settled into a groove with Mitch Rapp-style protagonists navigating international conspiracies. I'd guess the latest one follows that pattern—a lone operative uncovering a plot that threatens national security, racing against time while dealing with bureaucratic red tape. The details get fuzzy for me after a point because the formula became so predictable.
Maybe I'm just jaded, but I remember the plots blurring together: a rogue state, a stolen weapon, a betrayal from within. He writes competent thrillers, no doubt, but I stopped seeking them out actively. Checking his publisher's page would give you the exact title and synopsis, which I probably couldn't recall off the top of my head anymore.
