The Apocalypse Codex by Charles Stross (Books 2016, 8)
The latest of Charlie's Laundry Files series, and Bob Howard is being considered for promotion. To management. He has to go on a course.
As you can imagine, he doesn’t stay on it for long. And soon things are looking pretty bleak.
It’s the usual Laundry fare: magic manipulated by technology, horrors from beyond the stars, intrigue, form-filling.
It’s great stuff, as always.
