Query: Extremely Disappointing

After many good or excellent books in the series, Dickson falls flat on his face. Final Encyclopedia was excellent; Young Bleys was decent; Other frankly sucks.I came very close to just giving up on the book, but I kept reading to find out what happens to characters I know. It wasn't worth it.The book itself is a slow-moving jumble that never really goes anywhere. At least Bleys gets laid.
