Overview
Rick Riordan's Camp Half-Blood Chronicles, the Greek/Roman demigod continuity, chiefly following Percy Jackson, son of Poseidon, is one of the best-selling children's/YA fantasy franchises in history and this database's first contemporary-mythology YA universe, published continuously since 2005 and still active. The universe is deliberately scoped to the Greek/Roman continuity: The Kane Chronicles (Egyptian) and Magnus Chase (Norse) are separate candidate universes, connected only by crossover shorts and cameos.

Related universes
- Crossover The Kane Chronicles: Explicit in-story crossover: 3 short stories (“The Son of Sobek”, “The Staff of Serapis”, “The Crown of Ptolemy”) and their collection Demigods & Magicians bridge Camp Half-Blood and the Kane Chronicles; registered solely under Camp Half-Blood Chronicles per its own mirror-note obligation, not duplicated here.
- Crossover Magnus Chase and the Gods of Asgard: Magnus Chase is Annabeth Chase's cousin by blood, and Percy Jackson makes a direct in-novel cameo in The Ship of the Dead, a textually closer tie than the Kane Chronicles crossover, though Magnus Chase remains its own independent universe with its own protagonist and pantheon (Norse vs. Greek/Roman).
