I only knew (and adored) Laura Resnick for her funny, slapstick-comedy-like "Esther Diamond" urban fantasy series. And now it turns out she wrote this excellent epic fantasy trilogy a few years ago - why are there no re-issues (I got my copies second-hand)? Oh well, on to the books.
"In Legend Born", "The White Dragon" and "The Destroyer Godess" are about an island nation that has been ruled by foreigners for a thousand years and is now facing a rebellion against their conquerers and a civil war against the water-sorcerers that are trying to take over once the rebellion is won. At the center stands the war between fire-magic and water-sorcery, with lots of power-politics and guerilla-warfare thrown in.
What makes this trilogy so much better than the average epic fantasy are the characters: while there are still the standard warriors, sorcerers, aristocrats and peasants, Resnick wrote complex people with real personalities and relationships. They're not always nice. The villains are actually motivated (they don't do things just because they're evil) and the heroes aren't that heroic either because they make mistakes, get jealous or seriously missinterpret things. There are numerous plot-twists, well-written action scenes, political intrigue, good descriptions of the enviroment, witty dialogue and even a nice romance (that mercyfully stays in the background most of the time - this is definitly not a romance novel).
If you're willing to confront a very complicated plot and a big cast of characters you'll enjoy this trilogy very much. I did.
UPDATE March 2023: Re-reading the trilogy and it holds up very well. Perhaps even better the second time around when you can concentrate more on character-interaction than on keeping all the different plotlines straight. Highly recommended! (Still no re-issue in print, but at least there's an e-book edition now.)
