Just finished Charles Stross' latest Laundry book "The Delirium Brief". This one sees Bob Howard back as the main character, taking place directly after the events of "The Nightmare Stacks". Another darker book that takes the series down an unexpected track. After the aborted inter-dimensional invasion that has left thousands dead and Leeds devastated, the Laundry is outed and scapegoated, with the government intent on disowning and disbanding the secret agency now laid bare to public view. Behind it all is a secret takeover over of the US agencies and the UK government by the Sleeper. An old enemy returns, and Bob and what's left of the Laundry have to battle the puppeted government, an evil god from another universe, and will have to make a deal with the devil to keep the country and the world safe.
Once again, Stross turns in a darkly humorous and scary tale of our world on the brink of supernatural collapse, with only a top secret spy agency standing in the way. This time their enemies are not just the Evil Ones, but our own politicians and media. Things go badly... and then they get worse.
Another brilliant addition to the series by Stross, and if you've read the previous books, it's a nice return to have Bob back after he was sidelined for a while in the last two novels.
