From the publisher's website:
There are things in this world that come from somewhere else. Hungry things. They scrabble in the dark places, reaching out to draw in prey. Sometimes it’s human prey. Sometimes it’s the People.
One of those things is reaching out even further now. It’s built its nest somewhere unreachable. It’s subtle and cunning, enough so to hide its own strength. And it is strong, and it is dangerous. But it made a mistake. It began to hunt on your territory. It started to take people that are under your protection.
Now it’s time for you to do the hunting.
