Harry Potter and The Betrayal : Part One

In which Harry finds out about the betrayal of the Weasleys four years after the Cursed Child debacle, and proscribes apt punishment, before going back in time to fix things. I know this is cliche, but who cares! (completely over the top Weasley bashing, Ron Ginny and Molly specifically so if ya don't like that, stay away!) Rated M to be safe. HHR, NLLL
