Can you recommend some good 'Percy x Titaness fanfic'?

I'm not sure about a specific 'percy x titaness fanfiction' off the top of my head. However, you can try searching on fanfiction platforms like Archive of Our Own. There are usually a lot of unique takes on such pairings, and you might find one that suits your taste in terms of writing style and plot.

Love against all odds is a very prevalent theme. Given that Percy and the Titaness are not an ordinary couple, they face a lot of opposition. Their love has to overcome things like prejudice from others, differences in their upbringing, and the political implications of their relationship in the fictional world. Also, the theme of self - discovery is often there. Through their relationship, both Percy and the Titaness learn more about themselves.

One common theme is the clash of two different worlds. Percy, from his heroic and somewhat mortal - associated world, and the titaness from a more ancient and powerful realm. Another theme is often about redemption or change, where the titaness might be on a path to change her ways because of Percy.

Tethys could also be a candidate. Percy as the son of Tethys could have a connection to the oceans in a different way than his Poseidon - related powers. Maybe he could communicate with sea creatures on a deeper level or have the ability to control the tides in a more powerful way.
