With Lackey, she has a series with James Mallory that I've enjoyed -- about magic and such. I can't remember if it is the Shadow Series or the "To Light a Candle" series. They have a lot of elves and demons and such in them. I don't think there are any shapeshifters, but it's been a LONG time since I read them.

I like her elemental masters series too. "The Fire Rose" was really good. It's "historical" fantasy as the setting goes and they are adaptations of fairy tales in approximately 1800s to the early 1900s -- I don't think she's gotten to World War I yet (but I'm not reading them for that sort of thing). Usually light romance in those. NOTE that there are shapeshifters in at least some of them -- the one that I just read (Blood Red) was about werewolves.

Oh, and the Lackey ones with the kingdoms with the fairy godmothers are good... extremely light.

Umm, for sci-fi, I like the Timothy Zahn books about Star Wars... he's very detailed and has awesome characters.

I love Victoria Holt novels too... The Fire Opal and Seven for a Secret were ones I liked.

I also went through a Gothic romance phase with some Reader's Digest condensed books this summer. Kind of fun for a change. :)
