This was written when my writing skill was more unrefined so don't criticize me in the comments about it please.
I know TONS of people have done books like this, but I want to try my hand at it.
The original seven demigods are getting older, and are about to leave Camp Half-Blood. Chiron thinks since they are very powerful, then monsters will attack them very often.
He thinks they need more practice in things beside physical combat. He contacts an old friend Minerva McGonagall. Albus Dumbledore is dead, and Harry and his friends are repeating their seventh year since they missed it. Then trouble arises as usual.
