Ben Aaronovitch is one of my 5 favourite authors - he is simply the best current urban fantasy author writing. If you have never read any of these books, do start at the beginning, or you'll miss a lot! I'm hoping for more on the German wizards...and now the American contingent, but I was very happy to have another book devoted to Peter Grant and his very peculiar London. Loved the Douglas Adams homage and the twisted timeline.

While I thought I was content to let the River of London series end with the conclusion of the Faceless Man arc, I'm glad to see that this series still has more to offer. Not as strong as the other books in that the mystery was easier to solve but it sets up plenty of future conflicts and complications that'll captivate magic and police drama lovers alike.

Another entertaining entry in the ongoing series. Aaronovitch is very good at funny one-liners and this book is well-written throughout. My only quibble would be he’s too heavy with the historical/tech content — he gets carried away inventing it and I lost interest trying to follow, as if we all had to write an exam on Ada Lovelace and the Mary Engine after finishing the book. That aside, fans of the series will enjoy this installment.

Another good Peter Grant story and it kept me engrossed through the entire book. It was a very modern day story integrating computers, programmers, and 3D printers into the story. It touched on some a character modeled a bit on the ultra successful tech entrepreneurs but also touched on the beginnings of computer development integrating them nicely into a magical story. That said I was let down by the ending a bit, it came on very rapidly and felt a bit contrived while most of the rest of the book went along nicely. So it will now be a bit of a dry spell but hoping for a new one in the series in the next year or so, possibly a novella with the German wizard in between.
