The Laundry books have gotten darker in a way I haven't entirely enjoyed, although that's my personal taste and not a criticism. This is another book where Stross attempts to write a female protagonist, and I find it pretty excruciating. Particularly the sex scenes.

Ironically what this book unashamedly is, is a love letter to Concorde. It's like reading a Neal Stephenson book: he's done the research and now you're going to know about it. And I loved it.

Can't help but think this book would read more easily with less snark.
