This is my first fanfiction on this site, so any constructive criticism would be much appreciated!

WHAM! I slam into the hard, cold ground. Having just fallen onto the ground with no memory of how I got here, I decide that the logical thing to do is to get moving as soon as possible. Who knows what could be happening just beyond my field of sight?

I sit up, and immediately my head explodes. I scream, and fall onto my side. Pain, pain, pain… and still no memory of the previous events. However, my eyes manage to find a fuzzy shape that is getting closer with every passing moment.

"Hey, Ray?" the shape says. "Ray? You OK?"

Rubbing my head, I sit up for the second time, and for some reason the pain ceases. A girl, about the same age as me, is standing next to me. She looks kind of pretty, with long blond hair that's braided down her back.

"Hi. Erm… who are you?" I ask.

She giggles. "My name's April. Do you know where we are?"

"Nope. No idea." I say. "So what do we do?"

We look around. The landscape looks very fresh, with green as far as the eye can see. It appears as if we're at the bottom of a valley, so we can't see very far either side. However, the trees that are growing here are huge, and they look fairly weak. "Should we try and make an axe?"

"OK" says April, and she bends down. When she straightens, in her hand is a sharp rock. "I think this is a flint."

"That can be the head, then. I'll get a stick. Can you find some vines?"

A few minutes later, we have constructed a makeshift tool. The trees that we hit topple very oddly, toppling on top of me, but splitting into tiny fragments that I can easily collect. I notice that April has two backpacks, so we take one each and then I have an idea.

"We should probably make a house before nightfall. I get the feeling that something bad will happen when it gets dark."

So just as darkness begins to fall, April and I have built a house out of wooden planks, and barricaded the door. I discover that, with a flat wooden surface, I can suddenly construct a much larger range of products. I make a table and two chairs, and April and I settle down for some discussions.

"How old are you?" she asks.

"I'm fourteen," I reply.

"Same!" she exclaims.

Suddenly, a thought strikes me. "How did you know my name?"

April looks awkward. "Well… you're my Guide."

"Your what?"

"Guide. I'm not sure how, but… every time I look at you, I think… you're meant to help guide me through whatever comes."

"Well, whatever this means, at least we're not dead. To new beginnings!" I wave an imaginary glass in her direction, and she mimics my action, clinking our hands.

I'm just about to comment when suddenly our barricade explodes. I lurch across the table, tackling April, and pinning her to the floor. No shards of wood come near us, but I hear a moan, and turn around.

Oh no.

Zombies.
