Query: He just rushed it out - jumbled and poorly constructed

The first book was well written and kept one's interest - but the second fell flat. Makes me think he had a deadline to make and just typed enough words to get the book published. The story disintegrated about midway through. I usually really enjoy Gene Wolfe's writing - I would like to see him go back and do a good version of this book someday.
