Oooohhh. *is holding breath* Vampire stalker...BWAHAHAHAAAAA (evil laugh)
*hem* er...yes.
I have to tell you, I don't usually go for vampire stories...because of the fact that the concept of vampires is based off a German demon - but I did open yours because my sister is writing a novel with the same title: Expect the Unexpected. It sort of caught my interest rather jaringly, so I read it...and I'm rather glad I did!
Enough nonsense. On to the critique! *straightens cravat*
Overall, a pretty good start to the story. I can't give you any points for originality because I know absolutely nothing about most vampire stories, so I don't really know what is actually original. The only one I've ever read was the Vampire's Beautiful Daughter, so there you go.
She was just thinking (more like hoping) that she would be able stay here in New York for awhile, longer then the two months that her family had already been here.
Parenthesis...bad, generally, in fiction, unless you're adding them for humorous effect, which in this case I have a feeling you're not. If the statement in parenthasis is important enough to be mentioned in thh first place, then it deserves to be MENTIONED, not stuck inside a little parentha-cage.
The whole first part of this is slightly info-dumpy...as in, you're giving us a LOT of information at the same time. You might try going for an artsy effect and adding little paragraphs of information interspersed with Elizabeth's musings as she watches the rain, or something. That might break it up. Or you could just find an original way to put that information into your story. Maybe have the vampire add some of the info later when he's telling David about Elizabeth, you know?
One more thing about this section...you're using "she felt" and "she thought" a lot. This doesn't do a lot for the reader. The reader doesn't get into a story where we're just TOLD what they feel...we want to, in some sort of small way, feel what they feel, or at least sympathize with what they're feeling.
For instance, instead of saying "She felt confused" you could go into a lot more detail and perhaps provide graphic images for the reader to put into their minds: "She felt as a mouse feels when it has wandered out of the corn fields of Kansas and into the middle of New York City - deserted, bewildered and utterly lost." Obviously that's stupid, but you get the picture.
Also, it seemed a little nonchalant and casual, how you just casually threw in the whole vampire concept...I mean, I don't know what your society here is like, but if I found out my father was in trouble with a bunch of vampires, I certainly wouldn't believe it until one came up and started sucking out my blood. You know what I mean? So either make it clear that your society does include vampires and accepts them, or make the fact that her father is involved with them a little more startling to her.
Okay, for the first section, that's about it. It seems like a lot, but really I'm just long-winded and use a lot of words to say very little. Ignore me.
Moving on...
What the hell are you talking about Josh?
Comma after 'about.' "What the hell are you talking about, Josh?" Good startling first sentence, by the way. In fact, it might be better to start with this scene and then go to the whole Elizabeth scene. This sentence catches my attention much better than your other starting sentence.
Not looking very happy at being bothered.
That's a sentence fragment. Either connect it to the sentence before it, somehow, or lengthen it into a real grown-up sentence. "The man didn't look very happy at being bothered," for instance.
"Well sir, I'm talking about that man, you know the one that betrayed vampires everywhere? You know, the same one that killed half of our kind, twenty or so years ago?" the man standing said, he looked to be in his late teens and rather terrified at the older man's outburst.
Okay, first dialogue sentence seems quite...er...casual? For the content. He's just SAYING it like it's normal..."yeah, you know that one guy who exterminated half our race? Well, he's here." Isn't that a little casual considering the circumstances? Also, since previously you referred to the male vampire standing up as a 'boy' it might be better to continue doing so.
Also, don't connect your dialogue sentence with the description. Let me explain. What the man is saying has nothing to do with his appearance or whether or not he's terrified. (another point: can one be 'rather' terrified? Terrified is a very extreme word, there's no 'rather' about it. Anyway...) You don't put two unconnected things in the same sentence. "The pig ate the pizza, the girl had green eyes and a stony expression" doesn't make sense! It's the same with your sentence.
So a quick fix? Take out the description of the boy and put it in earlier, before he says anything. You can use it to highlight his state of terror, in fact, like this:
The standing teenager cringed, green eyes widening at the man's outburst, but he forced his stiff lips open to answer. "Blah blah blah," he said, etc.
See what I mean?
ANYway...
He no longer seemed scared of the former, even though he was capable of killing him for being disturbed.
I would really strongly suggest giving at least one of these people names and then USING it! Who is he? Who is him? Who is capable of killing whom at what time...for what? The former from what? If 'he' is the latter, is 'him' the former? ACK! See what I mean? We know the teen's name is 'Josh,' so take advantage of that and use at least Josh's name to help clarify above sentence.
"Why not?
Quotation mark after question as well as before.
OKay, well, as far as I can see from there on you're pretty good grammatically - your dialogue is awkward in some places, but I would just suggest you read through it aloud, putting commas where you pause to take a breath and stuff like that.
Also, through the entire first part of the vampire scene, you never once refer to Josh as Josh, always as the boy, or the teen, which makes it very confusing when David comes in and is referred to also as the boy and the teen.
Don't be discouraged when you see the length of this critique! It means your story was worth it! Please keep on posting, and I'll try to keep on adding my two measily little bits worth, and we'll see where it leads, eh?
Just remember, all of this stuff is just advice. You can take it or leave it or ball it up and throw it to the dogs, it's entirely up to you. Overall a great story and I look forward to reading more...
