What is next?
I am afraid that may not be hard to guess. Haryy's family isgoing to be sooo so sorry for what they did to him. They will help him get in touch with his feelings, so he can forgive them and find love and happiness. I see a lot of angst in future chapters because after Voldemort is gone he has no more purpose. 'Wrong BWL' stories have verylimited possibilities for plot. I would be surprisd if there would besomething new.
Your writing should deserves a better plot. Be creative. Don't write clichè.
