I enjoyed the white Tiger TPB. I probaly would have stuck with the character because the trade felt like her Tortall novels, very much the intro to a trilogy or possibly a four book series.
But, crap what a waste to kill her off in a single page. Marvel is even worse than most companies for dead does not mean dead, but as they have not asked for Pierce to come back and do more work for them it feels like this character will not be back.
I echo many of the other post that Protector of the Small is excellent, and that Trickster was annoying.
