Fanfiction still feels like home for this pairing. The tag system is messy, sure, but you can find archives of stories from the mid-2000s there that you won’t see anywhere else, and for Artemis/Percy, that’s where the classics live. A lot of writers who grew up with the books started there, and there’s a certain rawness to the older stuff I haven’t found replicated on newer sites. The search is a pain—you have to filter through a lot of unrelated Percy/Annabeth or general Percy harem fics—but stumbling on a well-written, decade-old multi-chapter that explores their dynamic as rivals forced into an alliance feels like digging up a relic.
AO3 is where the more polished, thematic work tends to gather now. The tagging is a lifesaver for finding specific tropes, like ‘Slow Burn’, ‘Enemies to Lovers’, or ‘Godly Politics’. You get more experimental takes, too, like crossovers with ‘The Witcher’ or AUs where they’re both mortal university students. Sometimes the prose gets a little too ornate for my taste, losing the snappy dialogue that makes their interactions fun, but the hit rate for complete, thoughtfully characterized stories is higher.
Honestly, I check both. FFN for the nostalgic, foundational epics and AO3 for the newer, trope-specific deep dives. Tumblr and Discord servers are good for recommendations, but the stories themselves usually link back to one of those two.
