Got an ARC of this from Edelweiss after missing out on a copy at BEA. And maybe it's because I'm a writer and I love reading about the writing process, or maybe it's the surreality of reading a book where the characters attend BEA, but I really enjoyed this. It's a massive departure from Westerfeld's usual style and genre, but once I realized how the structure works, and how the Lizzie parts do and don't relate with the Darcy parts, I found it quite fun. Recommended, with caveats.
