Pretty meh.
It's an odd concept that a 'thriller' should be so padded and uneven, but this is one such great example. It starts off quick, with a promise of biological terror that was eerily reminiscent of COVID despite being published before that point in time, and overlaps with the ending of the previous book in a creative and clever way to tie events together. Quinn's relationships and standing are established, the problem presents itself early and the tension amps up...
And then things drag, on and on, as we see the problem from other perspectives. Victims, civilians, soldiers, all show their own sides of the problem to suggest the scale of this catastrophe. The problem with this is two-fold, though. One, we never see these people more than a few times, sometimes even just once, so we can't really sympathize with them or care what they go through. Second, this happens well into the end of the book. The last hundred pages and less has new characters popping up just to show differing perspectives of events, and rather than ramp things up and keep the adrenaline high, all that does is pad things out.
Speaking of padding, there's more of it here than at Wonderbra warehouse. First, there's a LOT of weebery going on here. Japanese culture was huge and cool back in the day, but since everyone and their cat is doing it, the best I can manage for interest is halfhearted at best. And it drags on and on and on here, with side stories and descriptions galore like the author wanted to take a tour of the place and used the research for this book as an excuse to write off the travel expenses. We see a lot, meet some people and most of them die. It could have been cut and little of value would have been lost.
Second, characters spout descriptive dialogue and offer their stories unsolicited and without even a clear reason for doing so, using up whole chapters where a few pages would have done, and it's all in the service of... actually, damned if I know, because I wasn't engaged or amped up. Those sections just let me down to an idle, and that's not good for a 'thriller.' Worse, some parts were utterly unnecessary, with new characters popping up just to be there and extend the page count while other threads were left hanging. And that ending? A quick turnaround from a character I forgot and didn't care about, and a twist that I was utterly indifferent to thanks to the pointless melodrama up to that point.
And all this really sucks because there's parts of a good story here. The tension between Quinn and his ex, the ties among him and the other agents, the larger threat spreading across the world, shadow ops and spy stuff is all the bread and butter of fiction. There are some great characters here that could really make their mark on the series if they were allowed to branch out and breathe. But rather than making good on that, we get a book that consists of 'Quinn gets attacked, gets a lead, and leaves to follow it. People fight and die. The end.' And this takes almost 450 pages to pull off. Thrilling, truly.
Could have been a hundred pages shorter and it might still be mediocre, but at least then it would have taken less time to get through. 3/5.
