Fire and water don't work - Leo Valdez

Adaliah Asturias is the daughter of Poseidon, she arrives at camp half-blood and is immediately annoyed by a short, mischievous boy, a son of Hephaestus but when she realises he's not so annoying she wants to learn more about him, they become good friends but both of them want it to be something more, however her father doesn't approve...

I do not own any of the characters except Adaliah. Rick Riordan owns the characters.
The 'mature thing is only on for violence and mild swearing. No smut.
