If you enjoy the Laurell K Hamilton books, there's also a message board on her website--I believe it's laurellkhamilton.com, but I can't swear to it. If you're into the books for the sex, the last two, Narcissus in Chains and Cerulean Sins, have LOTS of sex. It's kind of ruining the series for those of us who like a PLOT, but the books before those two are pretty good. My favorite is Obsidian Butterfly--you may even need to check that out ahead of time. As long as you know who Edward is and what the "marks" are, I guarantee you won't be too lost.
