Weak pick; the setup and middle were, due to elements in the plot (I deal with tech bros in real life let's not make me deal with them in fiction) , slow and not super interesting. Picked up at the 75% mark and did a bait-and-switch only topped by the first novel of the series (Rivers of London). So the average is still a passing grade, but I would only assign 3 stars if I did assign stars.
