Rate this book
The occult whispers empty promises. What it delivers is Hell.

From the author of Evil Unleashed and Demons Unleashed comes the most chilling collection true accounts of demonic possession, oppression, cursed objects, and all manner of encounters with dark forces from the deepest reaches of Hell.

In Hell Unleashed, John Harker rips the veil off polite skepticism to expose terrifying stories drawn from history, eyewitness testimony, and the front lines of modern exorcism. These aren't Hollywood inventions—they're the horrifying realities faced by ordinary people who opened doors they never should have touched.
