I haven't read L.J. Smith.
Between Meyer and Stolarz I'm definitely going to say Stolarz. I couldn't finish Breaking Dawn because it annoyed me so much, and I always finish books.
I have a copy of Blue is for Nightmares by Stolarz that I've read around 3 times. That's actually on the low side since I used to reread books more than I read new ones, but I did like it enough to read it three times. I'm too self conscious to check out young adult from the library, and her series in on my list of series to finish when I can find copies anonymously.
