Agrippina Greystone and her uncle travel to Blindburn-a small town with a big problem-at the behest of the king. Plagued by five young women mauled to death during full moons, the townspeople are convinced they have a werewolf, but the ever-logical Agrippina isn't so sure. Set in the 1790s, the opinionated and determined Agrippina finds herself traversing the prejudices of the time while trying to unriddle who or what killed the young women. Raised by her academic uncle Dr. Greystone, Agrippina was taught sense over superstition. But what if the logical answer isn't always the right one? With more questions arising at every turn, will she discover the truth, or will she come to find just how sharp the teeth of the wicked are?
