So, I'm too lazy to write a legit review of this and will settle for a tiny little blurb with the snark cut out of the equation.
This book had:
-imperfect characters that grew on me; complex characters
-dystopian setting mixed in with that hint of steampunk and much of that there-is-a-whole-other-world-out-there-I-don't-yet-understand charm
-predictable, but enjoyable story (Finn's identity, the cube, Sapphique escaped and is the nine-fingered dude, Warden is NOT Luke's Claudia's father)
Basically, it was a good time and I'm cursing myself for not buying the second book with this one.
