The Mix-Up in Number 12 Grimmauld Place (Rewrite)

Nico was in the worst situation possible. First, he was tired as hell, thanks to his cousin. Then, he ended up who knows where, just because he couldn't handle his stupid emotions. And now, he was the 'prisoner' of a bunch of stupid stick wielding maniacs, who (by the way) were crazy as fuck! Will Percy and the group be able to get Nico back before everything goes up in flames?
