Percy Jackson made mythology feel alive and hilarious. If you've finished Camp Half-Blood and need more adventures where ancient myths crash into the modern world, these series deliver.
Both follow a kid discovering a hidden world, training with peers, and confronting a rising evil. Harry Potter is darker and more British, but the found-family core is identical.
Riordan's voice and formula carry over perfectly. If you liked Percy's sarcasm and the way Riordan weaves real mythology into action plots, this is the most direct follow-up.
Both feature kids dropped into a world of mythological creatures with rules they must learn fast. Mull's creature design is wildly creative, and the stakes escalate dramatically.
Both mix mythology with modern settings and a witty protagonist. Artemis is the anti-Percy - a villain protagonist who slowly develops a conscience - which makes for a fun change of pace.
Same Riordan DNA with a Norse mythology skin. Magnus is more laid-back than Percy, the supporting cast is excellent, and the Norse setting feels genuinely different from the Greek books.
