From a reader's perspective, I'm always curious to see if the first line of a book sets the tone for the story, if it fits with the vibe I've gotten from the cover and blurb, if it's unexpected or makes me just have to read more to see what comes next.
I love it when a book starts with dialogue, which is probably why a lot of my books tend to start that way. :) I enjoy being pulled right into the conversation and figuring out what they're talking about and what impact it's going to have.
A few examples from my books:
“What are you going to do, fire me?” - Primal Hunger
"Montana is dead.” - Whatever It Takes
“I thought you liked it rough?” - Storm Warning
I'm also a big fan of getting caught up in a character's thoughts right from the start and knowing that no matter how innocent a thought might be, a character's life is probably about to be turned upside down.
Here, kitty, kitty. - Primal Attraction
It all came down to a towel. - Dark Obsession
It was official—she was going to die shackled to a damn gargoyle. - Primal Pleasure
Of course I can't talk about first lines without mentioning some that I’ve read in the past while that pulled me right in.
"I’VE met teenage girls with more testosterone than that man has.” - Erin McCarthy, Flat Out Sexy
I’d die for him. - Karen Marie Moning, Fae Fever
“Live life balls out,” Katie Kramer told herself every night, and even though she didn’t own a pair, she hoped the mantra would keep the nightmares away. - Jill Shalvis, Instant Attraction
I didn’t realize he was a werewolf at first. - Patricia Briggs, Moon Called.
So what about you? Any favorite first lines (read or written)? Have you read any first lines that seemed weird or any that made it impossible to set the book aside?
