In the third installment of his ambitious “Holiday Spirit” saga, John DeGuire shatters the boundaries of traditional horror. If the first book was a localized New England mystery, “Monsters Arise!” is a globe-trotting, genre-defying epic that feels like a fever dream collaboration between Mary Shelley, Bram Stoker, and Jules Verne.

The narrative scale here is staggering. DeGuire doesn't just stick to the shadows of Vermont; he flings his cast across a map that spans the Arctic tundra, the Congolese jungles, and the Appalachian peaks. From the tundra to the tropics, this isn't just a change of scenery, it’s a shift in physics. By introducing elements of science fiction and high fantasy, DeGuire creates a “timeless contemporary” world where a vampire can ride a resurrected woolly mammoth without the reader blinking an eye.

Two paths of the ‘Heart of Darkness,’ the novel effectively splits into two high-stakes rescue missions that eventually collide. Following a brutal defeat, Count Dracula proves his mettle not as a villain, but as a loyal friend. His trek through the ice to save Saul Frankenstein is pure pulp adventure, featuring battles against Yetis and the twisted legacy of Dr. Moreau. On the other track in a brilliant bit of literary crossover, Sherlock Holmes and Dr. Watson join forces with the werewolf Aoife and the invisible man, Ralph. This thread leans into the mystery-thriller genre, taking the team to the Nubian pyramids and the African interior to face off against mercenaries and gorilla-guarded secrets.

While the monsters provide the spectacle, the human (or post-human) element provides the soul. The true “monster” of the third act isn’t a creature with fangs, but the cold, calculating brilliance of Professor Moriarty. The resolution is refreshingly dark and emotionally taxing; DeGuire isn’t afraid of “tragic consequences.” The obsessive pursuit of evil by Holmes leads to a climax that leaves the reader, and the surviving characters, genuinely scarred.

“Monsters Arise!” is a class in intertextuality. DeGuire treats classic literature like a sandbox, playing with these icons in ways that feel respectful yet radical. It’s for fans of Gothic horror who want their tropes deconstructed and reassembled into something entirely new. It is vivid, violent, and surprisingly heart-wrenching.
