I toyed with my drink, swirling the liquid around the frosted glass, and glanced again at the woman sitting opposite me in the cafe. There was a softness to her gaze, an artless grace to her gestures that belied the mass of circuitry crammed behind her ceramic eyes and the electro-muscles bunched beneath the glossy skin of her slender legs. She was too perfect. "So, you think you can...kill him?" I asked. "I would imagine so." She smiled, parting her red lips for a moment. "He is well protected, though." "Yes." I nodded. "I doubt a cyborg, even one as sophisticated as you, will get past his security." She chuckled and lifted an eyebrow. "They told you I was a cyborg?" She shook her head. "No, I am a little more exotic than that..."
I have to agree with Dr. Bob. I liked the establishment of setting and character before the hook. OSC is always saying the first paragraph is free. While I admit I don't entirely understand his meaning, I'll repeat what he says FWIW.
Good ending hook too. In and out in 13. Nice.
I might suggest adding an internal bit of character after, "I asked." That seems like a good spot to take a quick aside and let us know a little about the MC. Male, female, motivation, etc. However, in this case, I'm willing to wait for that info.
I agree with the others that it's a wonderful hook. I think the first sentence is great.
I wonder about the very last sentence. At first the woman under-promises. "I imagine so." And then she over-promises. Even though she says a "little" more exotic I take that sentence as meaning she's "a lot" more exotic. I would prefer something slightly more subtle.
Also the chuckle and the lifted eyebrow seem to be two different reactions to me. Amused vs. confused. I mean she might be amused and raise the eyebrow to act like she's confused, but then she shouldn't chuckle too. Maybe this is just me.
Keep in mind these are all thoughts I had after mulling it over for a while. When I initially read it I was thoroughly intrigued.
