Finally, Will can enjoy something that always seemed out of reach: a normal life with a real family. But part of Will can’t let go of Dr. Warthrop, and when Arkwright returns, claiming that the doctor is dead, Will is devastated—and not convinced. Determined to discover the truth, Will travels to London, knowing that if he succeeds, he will be plunging into depths of horror worse than anything he has experienced so far. His journey takes him to Socotra, the Isle of Blood, where human beings are used to make nests and blood rains from the sky—and puts Will Henry’s loyalty to the ultimate test.

When Dr. Warthrop fears that Will’s loyalties may be shifting, he turns on Will with a fury, determined to reclaim his young apprentice’s devotion.

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.

When Dr. Warthrop goes hunting for the "Holy Grail of Monstrumology" in 1888, twelve-year-old orphan Will Henry follows him to Socotra, plunging into depths of horror worse than anything he has experienced so far.

Their destiny is to fix history. Their dream is to go home. Living in a house that’s actually a gateway between the past and present, the King siblings have to be ready for anything. It’s a painful fact they discovered after moving to Pinedale eight days ago. Desperately trying to rescue their mother from an unknown time and place, brothers Xander and David have lunged headlong into the chaos of some of history’s greatest—and most volatile—events. But their end goal has continually escaped their grasp. And worse: Finding Mom is only a small part of what they must do, thanks to the barbaric Taksidian. His ruthless quest to seize their house and its power has put not only the family, but all of mankind, in grave danger. Somehow, the key to everything hinges on Uncle Jesse’s words: “Fixing time is what our family was made to do.” But how can they fix a world turned upside down—much less find their way home? At long last, the secrets of the house and the King family are revealed in the stunning conclusion to this epic series. “If you like creepy and mysterious, this is the house for you!
