Are you aware that there's a sequel? The Whisper of Glocken isn't quite as good, but it's still interesting.

Mostly I like how absolutely unprepossessing the Outlaw-Heroes of Slipper-on-the-Water look until their names are revealed, at which point Glocken gets a bad case of cognitive dissonance; I don't remember much else about the plot. But The Firelings is terrific.
