First Lines

As I work on revisions for my first novel and have started the second in the series, I’ve been thinking a lot about the importance of first lines.
I recently began reading a book by Tessa Dare, A Week to be Wicked. The title and the beautiful cover drew me but the first line truly hooked me.
When a girl trudged through the rain at midnight to knock on the devil’s door, the devil should at least have the depravity– if not the decency– to answer.
Now really, how could you not pick up this book to read after that?
That is the goal, we as authors, need to strive for. Perfection in a series of words that draw the reader into our stories and keeps them happily engaged until the end.
The first line is, to me anyway, the single most important thing we write. It starts us off on a journey of possibilities. Why is that girl walking in the rain at midnight? What drove her to knock on the devil’s door? Who is the devil? Where is the author leading us?
Do any of you have favourite first lines you’d like to share? I’d love hear them and whether the book lived up to that start.
Ms. Dare’s certainly did.
