The easiest way to find out about her many series is to poke about her web site until you find
this page - it list all her books in all her series... I like her Elemental Masters, Serrated Edge, Bedlam's Bard, and Bardic Voices best, although I have poked around in most of the others. Not surprisingly (although I don't know why - perhaps its just a matter of principle
), I disagree with JSWolf about the value of the Five Hundred Kingdom books; I find them to be uninteresting retellings of well-know fairy tales.
Just Kidding JS - I do appreciate hearing your opinions, even when I disagree with them.
