This a very interesting start. It has a genius hook to get you interested once you start reading, and it sustains your interest through the whole thing. Also, I like the idea of the main character essentially being a tool of the bad guys, but is trying to thwart their plan by not letting them use her. It's very smart.
Oh, and just a little grammar/spelling error; you forgot to put a ' in wasn't. You wrote wasnt instead.
Other than a few spelling and grammar errors, this was very good. I'm quite curious to see what will happen in chapter one.

WOAH, talk about an exciting premise! I love the idea of a human being grown as a time bomb to spread an epidemic - it's very up-my-alley! This'll probably be a short review just regarding plot, because your writing style appears to be sound.

It's very easy to get caught on the high of an idea and forget about the actual logistics of the story, so you have to watch out for that. You say you'll go back and change stuff once you write more, which is great, so here's a list of things you should probably look into when you're doing that.

Xcore's plan:
So these people want to eradicate all life using their viruses? Brilliant. But, it's not developed as to why they'd need Sammy. Why do they need to spread the diseases via a human they created? Why is it not possible to simply release the viruses into the world, airborne or otherwise, while they stay in their safehouses? It seems a far more simple solution. Additionally, if their plan succeeds and the virus infects the entire planet, how will they leave the safehouses? How will the new breed of humans they make survive the disease - and how exactly do they make them incapable of sin? It's fine to keep these things hidden until later - just not too far later! They should seem like secret plot threads, not plot holes.

The disease:
How exactly does killing Sammy suddenly make the virus airborne? It's not really how they work - and the spreading of the virus through just touch is even more confusing. It would be fine to just explain away using some fake pseudo-science of science fiction, but at least acknowledging it would be appropriate. Most normal viruses can spread from victims whether they are directly touched or not - just being in the vicinity is risky.
This also beings us back to the part where xcore wants to infect the whole world, and you say that if Sammy dies then this will happen - so why doesn't xcore kill Sammy themselves? They could do it remotely while keeping themselves safe, couldn't they?

These are just a few questions that I found myself asking. They're not going to stop me reading the story, so perhaps they're not that drastic. The concept of an epidemic trapped in a 16 year old is a brilliant one for young-adult + dystopian writing. I also wonder, if Sammy was created and lived in xcore her whole life, where did she learn to love the world and want to save it? Would be fun to explore layer

Hi there Zrillis,

I'm dropping by for a short review on your piece here. I'm going to start with some nitpicks, move on to positives, and then move to some critiques. Let's get started!

The ultimate goal of their plan is to eradicate all living life, and create a new world.

all the diseases inside me will become air born

I will leave more notes as to my whereabouts, but I can not reveal my location.

I will attempt to find an airtight safe room, a place where I can be locked in forever. If you are reading this note, follow the news. I will leave more notes as to my whereabouts, but I can not reveal my location. My final letter will be left at the door of the safehouse I find, you must lock it, chain it shut, just keep me inside.
