Interesting encounter with the Dursleys; very good reading. But while I can understand Harry trying to run at the zoo and even knocking himself out, why would Harry do as his uncle told him? Why wouldn't he right then and there push the button on the Recaller? Perhaps Vernon had tied him up or something?
Yes, finally someone gets Fudge's start in office right. So many fics have him as MoM during Voldie first reign of terror. Good job there.
Why would Arabella, given she lives in a house full of cats, be rusty on the cat language?
This is one of the better (if not best) pre-DH portrayals of Dumbledore that I've read. Though I wonder about the, never-been-physically-abused and didn't-know-about-the-abuse parts. Dumbledore, though it broke his heart, allowed the abuse to keep Harry alive under the blood protection. DH certainly shows the power of the blood protection (which many stories have sneered at). Dumbledore would've viewed it as a tradeoff for the 'greater good.'
Anyway, this is quite good. I enjoy reading.
