This short novella explores the history behind a tome of eldritch forgotten lore from the so-called "First Age." It's found by an order of monks in service to the Spanish Inquisition in 1498. Naturally, the Inquisition seeks to destroy this demonic book, but is unable to do so. It resists all attempts at destruction, shrugging off fire, acid, and even repeated blows from an axe.

This novella explores what Nikola Tesla was really up to at his Wardenclyffe facility on Long Island in 1903. Obsessed with providing cheap wireless power, his experiments yield success, but at a terrible, terrible price, tearing a hole in reality

In the years leading up to World War II, Japan was attempting to establish itself as a leading world power. To do so, a secret order of monks seeks to reclaim the power of the Black Wind, which was powerful enough to stop the Tokugawa Shogunate from destroying the secret order. They hope to use the Black Wind to completely dominate the world.

The structure of this book is a bit odd because it changes between first-person perspective when the viewpoint character is the American Frank Slater and third-person perspective for any other viewpoint character. It's classic F. Paul Wilson style of writing, though, as he shows us the viewpoints of both heroes and villains in the story.

Two groups of Nazis find themselves trapped in a mysterious keep in the Transylvanian Alps while an ancient horror hunts them down one by one. They are so desparate they turn to a Jewish scholar to help them defeat this evil being, who is more ancient than he claims. Meanwhile, a servitor of another cosmic entity travels to this keep to stop the ancient evil he had locked up there over 400 years ago.

This is our first introduction to Rasolom, the major villain of the Secret History going forward. Here, he's portrayed as a former boyar of Vlad Dracula, though his backstory reveals he's something much more ancient and evil.

Glaeken thought he'd stopped Rasolom in the keep. He was wrong. Now evil is stirring again in a small town on Long Island in the 1960s. Jim Stevens inherits a multi-million estate from a Nobel Prize-winning scientist, then eventually discovers the truth behind the scientist's experiments. The end result is that the One is returning to the world again, seeking to claim it for the Otherness he serves.

This is a collection of short stories that all touch on the Secret History in some way or another. For instance, "Demonsong" recounts the battle between Glaeken and Rasolom during the First Age in a sword-and-sorcery homage to Robert H. Howard.

My favorite story in this book is "The Barrens," where a woman is contacted by an old friend to explore the Pine Barrens of New Jersey, looking for clues that will lead to discovery that threatens to shatter the boundaries of reality itself.

Repairman Jack is F. Paul Wilson's most popular character. He wrote several short stories about him, giving readers more insight and background into Jack's day-to-day life. He's a "fixer," an urban mercenary lurking in the bowels of New York City's underworld. On paper, he doesn't exist, having no official documentation whatsoever. If you need help that no one else can provide and if you can find him, he might be able to offer you a repair job--for a price, of course.
