Book 4 was of A Student of Wants to Live. This book takes the series much darker and leaves us with more of a horror/LitRPG than previous books. The story takes us to America, however it should have been set in New York instead of DC, that one change would have made the America part a lot better. Be aware that the explicit language is much higher, especially during the America scenes. Overall, this was not my favorite book of the series as the overarching plot seems to be flagging somewhat. Not a bad novel outside of those items mentioned, we will see if this sagging overarching plot picks up the next novel.
