Things are hairy in River Heights this holiday season. Two wolves have disappeared from WildWolf, the federal wolf preserve just outside of town. Local farmers think the missing wolves are killing their sheep, but there are also rumors of werewolf sightings nearby. At the same time, the annual River Heights Winter Carnival is set to begin. When the first two days of the outdoor festival are full of tragic disasters, Nancy canât help but wonderâis there a link between the carnival's trouble and the missing wolves?
After the carnivalâs beautiful ice palace is destroyed, Nancyâs sure thereâs a wolf at River Heightsâs door. But is the leader of this pack of crimes human, or beast?
