This is the sixth book of the Laundry Files, and the first to be narrated by Mo instead of her husband. The plot keep me thoroughly engaged, and I enjoyed Mo’s voice — it was a nice change. I finished the book utterly wrung out, and I think that is probably a common experience due to Stross’ skill at bringing the reader into sympathy with the speaker. I think this is the fourth Stross piece I’ve read in the past couple of weeks, and it probably isn’t wise to immerse one’s self so deeply in this particular world! I’m going to have to step back and read something else for a bit as a breather.
