Percy Jackson and the mortal instruments crossover

Jace's pov

Demigods that's what's they called themselves I had no idea what that means so I asked "what exactly do you mean by demigods "Percy said" we're half Greek God and half human . Like my father is Poseidon and my mom is human and Annabeth's mom is Athena and her dad is human" i said " so who are the rest of your godly parents?" Leo said " I'm fire guy" "what" I said " Ugh... Boring....My dad is Hephaestus" and piper Said "my mom is Aphrodite " then Jason said " I'm the greatest of them all ( he said in a mystical voice) ( everyone laughed )
My father is the great Jupiter " hazel said sweetly " my dad is Pluto " and frank continued "  and I am the son of Mars "
