Overview
Rick Riordan's shared world of modern demigods, one of the best-selling children's and YA fantasy franchises in history, published continuously since 2005. Its Greek and Roman strand, Camp Half-Blood, follows Percy Jackson, son of Poseidon, through Percy Jackson & the Olympians, The Heroes of Olympus, The Trials of Apollo, the Senior Year Adventures and the Nico di Angelo Adventures. The Kane Chronicles moves the same world to Brooklyn and the Egyptian gods, following the siblings Carter and Sadie Kane, and Magnus Chase and the Gods of Asgard to Boston and the Norse pantheon, its hero being Annabeth Chase's cousin. The strands share one continuity: Percy and the Kanes meet in the Demigods & Magicians crossover stories, and Percy appears in person in The Ship of the Dead.

Co-credited 'Rick Riordan and Mark Oshiro' on their original editions; continues Nico di Angelo's arc directly out of The Trials of Apollo's ending, the current chronological frontier of the universe.
