Flesh-eating danger abounds in the chilling sequel to The Monstrumologist that is "as fast-paced, elegant, and, yes, gruesome as its predecessor" (Publishers Weekly, starred review).

While Dr. Warthrop is attempting to disprove that Homo vampiris, the vampire, could exist, his former fiancée asks him to save her husband, who has been captured by a Wendigo—a creature that starves even as it gorges itself on human flesh. Although Dr. Warthrop considers the Wendigo to be fictitious, he relents and performs the rescue—but is he right to doubt the Wendigo's existence? Can the doctor and Will Henry hunt down the ultimate predator, who, like the legendary vampire, is neither living nor dead, and whose hunger for human flesh is never satisfied?

This second book in The Monstrumologist series explores the line between myth and reality, love and hate, genius and madness.

"A page-turner of an historical horror that will simultaneously thrill readers and make them sick to their stomachs."—Kirkus Reviews, starred review
