So, I just finished (literally) Charles Stross' latest additional to the Laundry Files The Nightmare Stacks. And it is bunches of fun.
The Nightmare Stacks reminds me of a Tom Clancy novel. I've only read two of those, but it has that feel. A reluctant agent caught up in things, tactical maneuvers, and technical specifications. And reading about a dragon's technical jargon just makes me smile.
The favorite characters aren't in this one aside from side mentions. Dr. O'Brien is seen in passing, as is the BLUE HADES Representative on her way to the pool in a wheelchair. Bob Howard is unfortunately in Japan. So the main character is Alex Schwartz one of the Laundry's PHANG agents.
But it's not a vampire book.
I was reminded of two fictional invasions while reading this. One was a GI Joe cartoon where they go up against a group that uses biological versions of all mechanical devices. The other is Sliding Albion from The Authority comic books.
A recommendation before reading this are Stross' short story "Equoid".
It's been a while since I've this much fun reading.
