This was good in a different way from the first book in the series, Ashfall. This book was more focused on adventure and because of that, it was a tad more "adult" in nature. Of course, that didn't bother me that much. There were some scenes where I felt a little nauseous, but it did make the action that much more real (and honestly, more realistic). I'll obviously read the last book in the series just to see how this all ends.
