Anyone else who bought this notice if the typesetting was completely off for a large portion of the text? I'd expect that from an amateur job, but not from a professional company.

Mine was totally fine as far as I noticed. Maybe you just got a book with a printing error.

I'm going to have to go with Dragonman on this one, Yen Press is actually pretty good about keeping its stuff together so it was probably just some bad luck on your part.
