Query: Not his best work.

This book was long and at some points boring. The beginning seemed really good and then it just seemed to go nowhere. I really liked his other books: Wolf's Hour and Swan Song. Two of his best. If you liked Poe's "Usher" , then your probably like this continuation of the Usher story. Otherwise, try the other two first.
