I loved the first one, I found it interesting and different. This one, though, I'm just finding sloggy. I have a few basic requests when I'm reading a book: unless it's some kind of twist, I generally like knowing (a) what the story might be about, (b) who the main character is, what makes them tick, what do they want from life, (c) what's going on right now, and (d) where are they? And, at least for the first 50 pages, I felt that I only got about 22% of the answers I was expecting.
Sometimes I'm willing to play along (i.e. when it's Gene Wolfe, and even then only sometimes) because the magic of the story might be getting those answers. But in this case it just felt like lazy writing, as if the author knew what/who they were writing about, but forgot to put it on the page for us. And since life is short but my bookcases are full of unread works, I'm moving on (I recently sorted my "Want to Read" in order of priority, which I carefully, one-by-one, decided for myself, and it's almost as much fun as actually reading them. Next up is Augustus Carp).
(Note: I'm a writer, so I suffer when I offer fewer than five stars. But these aren't ratings of quality, they're a subjective account of how much I liked the book: 5* = an unalloyed pleasure from start to finish, 4* = enjoyed it, 3* = readable but not thrilling, 2* = disappointing, and 1* = hated it.)
