Yes, indeed, this is a difficult adventure. It will likely take you many tries to get through this one. It also quite well written. There are good details throughout the story, and I felt like I was in the story when I was reading it. There is a lot going on with this story and it can be entertaining, but yes, the subject is terrorists in the Wal-Mart, so if that's a problem for you, you probably shouldn't be reading this one.
