How is it that some authors grab you by the sleeve and won't let you go, while others only provide a pleasant diversion that can be set down at any moment to do something more pressing?
I started my second Laura Lippman book this morning, and already I'm hooked. Barry Eisler does it as well. It could be in Lippman's case that she writes as I think, pulling up details that seem like they came from my own brain, but in Eisler's work I have no frame of reference, being neither Asian nor a hired assassin. So it must be something else, and I call it atmosphere.
The great writer creates for the reader a world that her whole consciousness enters into, and it's like life--you need to know what's coming next. There isn't any one thing that makes it happen. It's a tapestry that's slowly woven into a recognizable pattern, but you're not looking at it, you're part of it. Which is why we're a little sad when it's finished, a little less than what we were for that brief span when we were both readers and participants in the story's unfolding.
