Lisey's relationship to Scott, I thought the same thing. What the heck did she DO with her life, other than being Scott's "gal-pal"? Me, I'd be bored out of my mind stuck in that big old isolated house with no children, job, hobbies, or real identity beyond that as a wife. I found the fact that King felt the need to point out that Lisey was a slow reader a bit insulting, too, and what's up with teaming up Joyce Carol Oates with a bunch of romance novelists? Not that there's anything wrong with romance novels, of course - heck, I read them and enjoy them on a regular basis, but it seemed to me that the purpose of naming Scott's and Lisey's favourite writers was to illustrate a fundamenal difference in taste and approach to literature. To me, Oates is right up there with Margaret Atwood and the rest of Scott's favourite writers. No biggie, but as a massive Oates fan, it confused me a bit.
Still, I felt that the character of Lisey was very well-crafted as a whole, and as much as the "stand by your man" thing irritated me - after all, I am a feminist - it didn't stop me from enjoying the story. Perhaps some time, King will have the courage to portray a woman writer, thus blending two of his reccuring themes into one? I'd be very interested to read that story.
