I read anything that's nailed down, or even just moving slowly. Cereal boxes, candy wrappers, all genres, etc., and I don't always have much time for arbitrary distinctions like literary fiction vs. genre fiction.
I'll admit it: I don't understand this book. I couldn't tell who was speaking sometimes, I don't understand how the Evas fit (or their relationship to Imp), and I don't understand even whether there WAS a narrative arc, let alone whether it was good. The nonlinear structure didn't help in this regard.
