If you listened to the first audiobook it's more of the same. And much like the game, it focuses more on infantry than mechs or vehicles. A good chunk of it is out on the stellar jockies youtube, I'd give it a listen.
As for the general plot. It focuses on one of the killteams sent to a corporate world that the SNC was based out of, with the purpose of killing the brigadors from the first game.
