This little book is a novella set in the Laundry universe (but before it went kaplooey).
It’s fine, I guess, but it just felt a bit… I mean, it’s about how Hello Kitty is a demonic presence (sort of), and that’s it. If that premise makes you chuckle, then you don’t even have to read the book, because it doesn’t really develop the concept any further.
But I mean, it’s fine.
