Query: A tragic disappointment.

I loved Gaiman's work on Sandman, among other titles, and thus eagerly awaited this novel. Never before have I been so frustratingly disappointed. Neverwhere is predictable, clumsy, garbage -- unworthy of such a normally original and creative writer. I recommend any Gaiman fan stay away from this book, as it may irrepairably damage their opinion of him.
