What’s in it?

Products & advertising1/5
Why this rating?

Prominent tie-in with broader franchise merchandise, though the text itself is a stand-alone story.

Death of a character3/5
Why this rating?

Death is an important theme: Hazel died and was resurrected, Thanatos is central, and characters face sacrifice and threats to the gods and world.

Graphic injury1/5
Why this rating?

Monsters dissolve into dust or essence when defeated; injuries are described but not overly graphic.

Strong language1/5
Why this rating?

Occasional mild name-calling or mild exclamations, but no strong profanity or slurs.

LGBTQIA characters1/5
Why this rating?

Subtle hints regarding secondary character identities, but not a primary focus of the narrative.

Religious themes4/5
Why this rating?

Central theme involves Greco-Roman mythology, deities, and prophecy as fundamental plot elements.

Romance2/5
Why this rating?

Developing adolescent crushes and supportive bonds between the protagonists; mild and age-appropriate.

Frightening scenes3/5
Why this rating?

Monsters, Gorgons, dangerous quests, a captive death god, and attacks on demigod camps create sustained but fantasy-based tension.

Violence4/5
Why this rating?

Frequent fantasy battles with monsters, gods, giants, and camp attackers; characters fight to protect others, though violence is adventure-focused rather than realistic.
