Agent Kal Hakala, who has been running the Bureau of Supernatural Investigation as its temporary director, has his hands full. First there was the windigo crisis that threatened humanity with extinction. Now he has received an anonymous challenge from a creature calling himself Maydock: “Come to Omaha within the next five days, or every day thereafter I shall kill ten humans in many inventive and disturbing ways.” Maydock has infiltrated BSI Security and can monitor Kal's every move, so until Ghost can repair the breach, Kal has no choice but to travel to the Heartland with no team backup and only those items he can carry. While Kal dances to Maydock's tune, Canton and his team covertly follow as close as they dare, realizing that if they are caught, they will trigger Maydock's epic murder spree. Even as Kal is put through his paces, he uncovers corruption so insidious it tears at his fragile sanity. With the odds stacked so heavily against him, how can Kal possibly vanquish the most powerful being he has ever encountered?
