Equoid: a Laundry Novella (Laundry Files) by Charles Stross
Downloaded this novella as part of Tor's freebie offerings of all their Hugo nominees for 2014. I knew nothing about the author, or that this was part of a series (referred to as The Laundry, I believe.) I'm not a major HP Lovecraft fan, so that tie-in with this work kind of left me flat. What I did enjoy was the idea that there's a clean-up crew out there for certain sorts of supernatural disasters (sort of like Men in Black, I guess) and that in this case, they're out to clean up unicorns run amok. Nice. Toss out the rainbows, sparkles, and virgins; it's all about life-sucking carnivorous beasties. Seems fair.
