I'd like to recommend "A Shadow on the Glass (The View from the Mirror, Book 1)" (and the rest if you like it) from Ian Irvine. (
Fictionwise spells his name wrongly) While the last book of the second series had a terrible ending (a fairly shamelessly bad "buy my next book" ending that turned quite a bit of the storyline upside down), I still sort of liked the story that lead up to it.
Oddly, this series has parts 2 and 4 available on amazon and fictionwise, with parts 1 & 3 missing, but considering that 2&4 were very recent additions, the rest might be coming soon.
