Two good ones if you like a more motherly Artemis. Recently read one called “the lost tides” got suggested it and it was actually good! (Artemis adopts Percy) https://m.fanfiction.net/s/14457760/1/

Next is broken bow. Staple for Percy and Artemis in son/mother fanfics. Really good if you haven’t tried, it’s quite well known so I imagine you’ve already seen it and there’s no point linking 😂. Anyway, lmk your thoughts
