Great book, mature teens and older
This is a great fictional murder mystery book. As an adult, I really enjoyed the book and recommend to anyone who enjoys murder mystery. It is fast moving, captivating action mystery that I could not put the book down. But now as a parent of advanced reading tween and teen, I hesitate to recommend to young readers.
It has graphic descriptions of murder scenes, ritualistic sex, cult rituals, corporal self-punishments, etc, which I would be very cautious about offering to young teens.
It has some cultish information on anti-Christian theories and views that may be very objectionable to people who are religious, and some other religious cult presence that are presented as facts (it took me some digging as an adult to figure out it's a sensationalized theory) so one needs to understand what is presented is fiction with some theory, and not a fact.
So until the reader is mature enough to get over those issues (or at least exposed to sex and violence depictions and are blasé about it), I would not recommend to teens younger than 17.
If you have read it before offering the book to a capable teen, well, you know what is on there. But if you have not read it yourself, consider reading it (it really is an entertaining book) before you offer it to a minor so you can decide for yourself if it is appropriate for them.
