On what would have been a normal Monday morning, quiet, normal, twenty-four year old Allyson Sanders receives a mysterious letter in the mail, informing her that she had inherited a house from a woman named Agatha Grimier in a town called Hollow Brook. Determined to unravel the history of this unknown relative, Allyson travels to Hollow Brook, where she discovers that she is the last in a powerful line of witches. She is shocked to learn she must defeat Thanatos, the cursed King of the Shadow Demons, before midnight on Halloween, or he would conquer the soul of every human being. Does Allyson resist the evil of Thanatos and defeat him, or will she be betrayed by the dark longings in her own heart?
