(Keep in mind... I really don't know how much my crit will help you. I'm still learning how to critique better)

But anyway, I would read on, personally. I already get a sense of what kind of person she is. Clumsy would be my guess. And I can tell she cares a heck of a lot about her camera and photography equipment.

I don't think you need "She always bruised easily." It takes up more word count. I think it would be fine if you left it as "The bruises were still there"

I'm not finding that much more right off the bat. I'm sure others will be of better help.

Oh, and one more thing to answer your question: That sentence you said you might include at the beginning "She had no idea how her life was going to change idea" It doesn't really make any sense to me. I think you didn't mean to include "idea" within that sentence. I don't know if that's a good opening line or not. Perhaps someone else would know better.

Here's an idea, though: try starting the story further on. You might be starting at the wrong place, but I don't know for sure. Start at some point where there's already conflict and the MC's problem, and maybe even a tension build-up. Plus, you start with a bit of backstory. Not that I myself find that a problem, but I think that was one of the rules. Not to start a story or book with backstory. The backstory comes later.

I don't think you necessarily need a hook line. If your title and book cover make it clear this is a story about vampires, you have enough in these lines to have me anticipating their appearance.

I agree with everything XD3V0NX said as well.

I'm guessing your MC had a photo gig there. Most photographers I know have protective bags and cases for their equipment, so she sounds like an amateur bringing in some extra bucks.

I hope you have a great story there.
