It's a lot of fun to listen to this (I love this series so much), but this is a terrible Emerson voice. I just can't buy it at all. He does not sound gruff or forceful or practically anything. :/
Her voice for Amelia is good, though. Probably going to switch narrators for the second book, since I have heard wonders about Barbara Rosenblat (and just listening to the sample made me think of Amelia Peabody).
