The Infernal Devices

Important characters die or face apparent death, with significant grief, sacrifice, mourning, and emotional consequences.

Descriptions of injuries and demon manifestations occur but are not excessively graphic.

Some mild cursing consistent with the period setting and YA genre.

A prominent same-sex romance and several LGBTQIA characters are meaningfully integrated into the plot and relationships.

Angelic, demonic, occult, and quasi-religious mythology shapes the fantasy world, but conventional religious practice is not a central theme.

Romantic relationships and the central love triangle drive major plot choices and character development throughout the trilogy.

Demons, monsters, possession-like threats, dangerous missions, captivity, and suspenseful attacks create a consistently dark and frightening atmosphere.

Kissing, sensual attraction, suggestive situations, and discussion of sexual relationships occur, but explicit sexual activity is not central.

Periodic mention of social drinking and the medicinal use of elixirs.

Frequent supernatural fights, weapons, abductions, torture threats, and peril involving demons and Shadowhunters; violence is consequential rather than purely comic.
