I read The Immorality Engine even though I didn’t think much of the first two novels in Mann’s “Newbury and Hobbes Investigations” series, of which this is the third. Somewhat to my surprise, I liked it better than the other two.
I still found the prose a bit repetitive and the plot low on surprises, but I thought Mann did a much better job controlling tone. (He also upped the gore quotient a bit, pushing the novel toward horror, which worked better than I might’ve expected.)
Most importantly, the relationships between the characters were far less static.
needs more demons? perhaps, but not as many as before.
