This was a fun take on vampires and fantasy lore. Initially, I was somewhat resistant to the way Hayes, and by proxy, Fred was describing Krystal. It read like a slightly less skeevy version of Jim Butcher's male gaze, making all women out to be sex objects and manic pixie dream girls, but as I read on, Krystal grew into a round and dynamic character. She isn't just pretty. She's pretty in a surprising way to Fred because of who they both were growing up, and that plays into her abilities and job requirements as an agent. I also really enjoyed that this series is set in a city other than New York, Los Angeles, or Chicago. I also am liking the vignette format. It reads like a connected collection of short stories, glossing over the boring parts of life. I'm looking forward to reading the rest of the series!
