Pacy and fun, in a silly-dark-Gothic kind of way. You can suck me in easily with hidden alchemical laboratories and outlandish quests and gender-bending teenage girls; but you lose me a bit with romance that feels forced and unnecessary, and with evil cripple stereotypes. I wanted to love the on-board wheelchair weaponry, but in the end I was left yawning at the evil-mad-crippled-scientist-with-a-cat thing, even if the cat was a somewhat awesome lynx familiar.Overall, though, I definitely liked it and would recommend it for a quick, fun read. Despite the grisly amputation scene, it feels late middle grade to me, not adult-young-adult.
