This sci-fantasy novel was a fun read. It faked me out a few times. E.g. for a while, I was pretty sure the title referred to the nursery rhyme about a cow jumping over the moon, but I was pretty far off. Also, I kept thinking "The author thinks he's so clever and insightful, but I already thought about this stuff over a year ago," …and then I remembered that's because I was reading the author's blog back when he was researching the book, so, uhm, yeah, I only thought of putting those things together because the author already nudged me in that direction.
