It was first published on October 12, 2010 through Simon & Schuster and is the second book in Yancey's Monstrumologist series.

[1] The book follows Dr. Warthrop, a scientist trying to debunk theories that vampires could possibly exist.

He's drawn from his research by his former fiancé, who pleads with him to save her husband from the flesh eating Wendigo.

Not believing that such a creature could exist, Warthrop ventures out and succeeds in saving his ex's husband, only for the man to then transform into a Wendigo himself.

[5] HorrorNews.net gave a more mixed review, saying that it "may not be as good as The Monstrumologist or really even a worthy follow up, but it is a book that deserves to have a second look if you did not like it after the first read like I did.
