I really enjoyed this too, even if I did think that there was a notable air of authorial panic about 2/3 in, when ALL THE IDEAS EVER arrived to overwhelm things a bit. I mean, an over-abundance of ideas is a state profoundly to be desired in authors generally speaking, but I do wish that someone had said BREATHE (and maybe save X and Y for a sequel). On the other hand, it was a very very good debut, I thought, and genuinely inventive and lovely. And yes: PRUNELLA.

Also very good recently was Aliette de Bodard's 'House of Shattered Wings'. Have you run across it?
