Book 1 of UnderVerse. This contains adult themes and language. That said it is a long book and there is a long slog through some of it. It is worth it if you don’t mind brutal killers. If the book was shorter I would not have liked it at all. That said there were parts I liked and parts I struggled through. Overall I did like it, but this is definitely not for everyone and I think a lot of people would not care for it.
