As Sara and Parsley begin to develop feelings for each other, disaster strikes, and Sara's younger brother Noah is snatched by the Witches. They must find him and set out across desolate moors full of merciless terror, to hunt the very creatures they've been hiding from. Can they succeed in saving Noah? Will Parsley and Sara's burgeoning love survive these bloodthirsty Witches? and, who can Sara trust in a world void of humanity?
