Sorry about the delay, I've been keeping an eye on my derailing thread on Chat while getting some writing done 
I'll post the (rough) synopsis:
Everyone knows that having a zombie plan is a great idea, and Sally Morgan was no exception. She kept putting it off though, always meaning to do it in a couple of weeks and yet never quite managed to get around to it. It was only a laugh anyway, wasn't it?
This morning, she woke up to find zombies everywhere and it's too late to make a zombie plan.
Now Sally has to make a run for it, making up a plan as she goes. The only problem she has now, is creatures just as strange as zombies are coming out of the woodwork and she's got to get out of the city and back to her family without getting turned into the living dead.
Sometimes, waking up sucks.

As of now, my characters are in a hotel (don't know why, it just seemed funnier that way) and have made it to the hotel kitchen for supplies, only to be nearly killed by a flying can of garden peas lobbed by a young couple who were hiding in the tin cupboard. It's taken 10k words to get there. I don't know why 
Busty I'm trying to get them to Buckingham Palace where a rather clever dude has covered up in plate armour (think Monty Python's Black Knight) and is quite happily lopping off various limbs in the middle of the Mall. At one point, he's probably going to pick up a severed limb and attempt to beat a zombie to death with it.
I know, I'm weird like that 
Thank you all so much for helping me with this! You're all absolutely wonderful :)
