I fucking love these books to death -- they're a light read, they're engaging, they're funny, and they have some serious issues going on which are quite thoughtfully engaged with. What with the glorification of mad science in steampunk, I love how this is a text in which it is openly acknowledged that science is every bit a tool of power and oppression and harm as religion is, where you know what? mad science isn't all that because sometimes it's wielded by fucking assholes and I don't think this is ever explored enough. Carriger's books manage to have this dark undercurrent even while being a funny comedy of manners on top.
But (as there always is in these things) one thing does bother me, and it's the plot device surrounding mummies from Egypt, introduced in Changeless.
