I didn't think this was terrible, but I agree that it didn't quite feel like Rowling's writing. Her stories don't usually have unnecessary filler and loose ends (view spoiler)[(who raised Delphi? What was her fate? She just sort of disappeared...) (hide spoiler)] and paper-thin explanations for things...(view spoiler)[(there is no actual reason that Harry should still be a parselmouth. Come on.) (hide spoiler)] It's a Harry Potter story, though, so I was mainly just enjoying having something new to read. I didn't care that the story wasn't crafted as well as the original novels; it was still entertaining.
