Woah this is awesome! Very unique premise! I love it!

Snape definitely should take Harry to the ritual site. 

Harry has his broom. They just need another broom and then they could fly. Or do zombies interfere with broomsticks?

The poor Muggle owner. Sounds like he's just given up.

I love how Snape refuses to call the creatures Zombies. 

Surely St Mungoes is working on a cure. Right? The Muggles reaction will be to just bomb and destroy everything. All the major cities once infected.

This is the read and cross-over I didn't know I needed. Thanks so much for sitting down and writing it down and sharing it! Such a fun story so far. I'm really enjoying it.

By the way, I edited the formatting of your story to fix the random breaks that were not indented.

Great start to the story. It was quite a breathless ride which suited the story very well, thank you
