First Line = First Impression?

I'll admit it. I'm a sucker for first lines. To me, as a reader, it doesn't matter if you have ten 5-star ratings at Amazon, killer reviews and readers handselling your book left and right. You have to snag me in that first sentence or I'll put the book back on the shelf (yes, I love eBooks, but nothing can compare to standing in a brick and mortar store surrounded by books–that is something an eBook will never, ever replicate). The same goes when I write. I want to snag the reader in on the first sentence.

So I thought just how much I like to employ the same technique in some of my books. So, check out some first lines from current books and even a few Works in Progress.

Current Books:

Flash of Dark: My head snapped to the side, vision blurring as my eyes watered from the shock.

Midnight's Ghost: Whoever said karma was a bitch wasn't kidding.

Blood Fever: He pleaded for his life.

Midnight's Shadow: If Wallace didn't kill us, I'd kill him myself.

Forged in Fire:  Two gallons.

Ragged Edge:  Dalton was damaged goods.

Impulse Control:  Today was the cherry on top of a shitty week sundae.

WiPs:

3rd Star Runner book To Be Titled: "Fuck it all to fucking fuckery."

Contemporary Erotic Romance To Be Titled: "Is she insane?"

So, what about you? How do you like your first lines? Do you think they leave a lasting impression on you as a reader? If you're a writer, what does the first line of a book mean to you? Oh, and I like first chapters too. But that's for another day.
