Well, I guess I'll be the first to say that this is a wonderful book--though I'm not sure how well-received it might be by someone who hasn't read the rest of the eleven books leading up to The Gold Falcon. Truth be told, I made the same mistake myself when I first discovered this series; I randomly selected The Red Wyvern (book nine), and found myself completely and thoroughly confused by the time I'd reached the second chapter.
It's well-worth the confusion, though--and really, if you start with the first book, Daggerspell, you'll get the hang of Kerr's writing style quickly enough.
These books aren't written in a linear progression (which, as afore mentioned, can create some confusion) she describes her method as being like a celtic knot in novel form: parts of the tale weave in and out of each other, with story-arcs that feature different incarnations of a core set of characters. The reader is left with a very eloquent and intriguing impression of the kinds of decisions and drama that affect us all, and the ramifications that echo through multiple lifetimes.
I understand that Kerr is an avid Dungeons&Dragons player, and it's pretty obvious in her use of Elves, Dwarves, Dragons, etc. I occasionally wish she'd get away from some of the more "cartoonish" aspects of these different magical races and stick with the riveting and more historically based medieval storylines in her books.
She's created a fascinating and well-fleshed out world in which people interact in a deeply compelling way. Over the course of eleven books, the reader has had the chance to walk a mile in the footsteps of every echelon of her society, from bondsman to Gwerbret or even King. I usually find it hard to put these books down, and I think I gobbled The Gold Falcon up in one gluttonous sitting.
Basically, if you've loved the series so far, you'll be buying this book no matter what, and I doubt you'll be disappointed. (I wasn't.) And if you haven't read any of Kerr's other books, I think I'd recommend that you start at the beginning. One gets the impression that Kerr has a very distinct destination in mind, and you don't want to miss one step of the journey.
