"Good story"
I enjoyed the story and the history it portrays. The narration uses a fairly passive voice throughout, for all characters, which detracts from the story.
"Long and cliche'"
I've listened to all of the Pendergast stories and Rene Auberjonois does a good job reading this one, but the writing of Pendergast stories is going downhill, IMO. Too full of of old cliches' (what is "living rock?")
"We loved the earlier books"
The new narrator should have listened to the previous books so the pronunciations were the same at least. The story and characters are still good, though.
"Had a hard time putting it down."
I stayed up late listening and was sorry when it ended. I liked the characters and descriptions of things as the mystery of the building unwound. A continuation of the story in another book would be great.
"Laughed out loud"
Liked the book, don't take it seriously - there is no great meaning of life here but parts made me laugh out loud during my commute.
