The previous volume in the series was one of the most intense, with the action running pretty much non-stop from start to finish.
So this one is a sort of breather episode. Several of the main characters were killed and wounded, so the guys we've gotten to know are getting whittled down. Sgt. Butsko, though, after a book or two being out recovering from wounds, returns. He has to reform the recon squad with just two other old-timers and a bunch of thieves, rapists, sadists, cowards, etc. drafted from the stockade.
Levinson does some great characterization work in this novel and it all leads up to one of his typically intense action sequences when the recon squad leads a reconnaissance-in-force into Japanese territory. We should be used to this by now--but not many of the recon platoon survive.
It's another strong entry in the series. I think there's only three more to go and one of the strengths of the novel is that I have no idea who will still be around when the series comes to an end.
