Tempest

'I said, this isn't forever,' I muttered. 'I'm only here because of that quest positioning.'
Dee grinned. 'Yeah, I know. And?'
'So why are you suggesting he... and we should...'
'He what? Likes you?' She rolled her eyes. 'And you should what? Get together? Be for real, dude. I'm suggesting it because you SHOULD.'
'No we shouldn't! Because I'm gonna leave soon, probably. And what then?'
'Not because you don't like him?' she teased.
I glared at her. 'I DON'T like him.'
'Sure ya don't.'

The Hunters are recovering from a terrible attack on their forces and Lady Artemis, but a new quest has been assigned - something the Hunters usually do. But they're recovering. So Camp Half-Blood sends its best demigods on this quest instead, since it's quite a dangerous one. Percy Jackson, Nico di Angelo and Thalia Grace (though she's the lieutenant of the Hunters, she insisted she was perfectly fine) are sent to West Virginia to complete this one. A dangerous Greek monster is out there causing chaos - the Clazmonian Sow. No Greek hero has ever beaten it. Well, except Percy in the battle of Manhattan, but that's exactly why they sent him as well.
The boar's angry girlfriend is back, and she's mega furious at being whacked and killed by statues activated by one specific demigod. But she can't find him, since she escaped Tartarus to West Virginia, so she's satisfying herself by causing chaos there. The residents are confused and shocked - and some of them can see through the Mist to what it actually is. They're Luxen, and they're covering up the chaos well, telling good lies and keeping the normal residents believing it isn't a supernatural pig monster.
Then the three demigods arrive, keeping their identities well hidden.
That is, until they meet the Luxen.
More accurately, until one sea boy meets one smug, kinda hot alien.
DISCLAIMER: I don't own PJO or the Lux series. This is a fanfic: all I own's the plot. Also: Katy and Annabeth won't be showing up. Sorry. I'm lazy.
