OMG, Elizabeth Bear's Carnival is full of awesome! It's got deception, love, double-crosses, shiny tech, and kick-ass women on the planet New Amazonia.
Vincent and Michaelangelo are interesting intriguing characters. Even though I doubt there's a sequel, I'd love to read more books with these characters. Lesa had her moments, but didn't have the same depth.
I ended up reading the second half of this book super-fast, with some late nights when I just had to find out what happens next.
