Is this too cliche or too much like percy jackson? Please be honest!?

i liked it personally but only when you got started in with the girl. i dont think its like percy jackson a lot but if you want to steer clear of tht you can maybe do something to where someone tells him and when he doesn't believe it they give him something and he remembers when he was like in third grade and back he had a mom or dad that was a god. just dont do Posieden. (cant spell his name) just givin ideas. or you could make it to where the girl or the little brother are the god and he finds out hes the protector
