4.25 A fun romp into computer nerdery that does not quite reach the greatest heights reached by the series, but doesn't fall short by much. The plot about the magical computing antiques is fun and even the big twist makes sense, even if we are left in the dark about much of the significance. The main problem I see though is the huge cast of characters that makes it hard to track all of them. Some of them only appear in third-person narration only to then jump back into the action. The mains are all interesting, but the supports are where it gets confusing some of the time.

As a side-note Aaronovitch shows really good representation once again. All in all, a very enjoyable read.
