Percy Jackson and the mortal instruments crossover

Jace's pov

So when I expected help what I had in mind was like 20 to 25 strong and tough looking men not 7 teenagers with confused faces
I thought they were Indians so I said "Namaste" when these did not reply I said "hey so you guys going to help us fight monsters"
The cute guy with sea green eyes and messy hair said " I guess so " I'm Percy " while while pointing at each of the demigods he said " this is Annabeth that's my bro Jason his girlfriend piper that's frank, hazel and finally Leo"
" so you guys humans or what" I said. The guy who called himself Percy looked offended. But he didn't get the chance to answer my question Annabeth ( his girlfriend I think ) answered " demigods , were demigods"
