What a disappointment. It would be easy to blame Mo but, if I'm honest, the plot is just flat out boring. I struggled to finish the book which is, easily, the worst of the series so far.

Charlie Stross does it again, and finally from Mo's point of view! The laundry files are the best series going in modern science/fantasy fiction, and each book makes coders try just a little harder to set up those summoning grids...
