In 1812, beneath the quiet Buckinghamshire hills lies the Hellfire Caves—a decadent lair of opium, satanism, and scandal for the elite. But when Antony Pennington, the warden, is murdered, his half-sister Dora, a fiercely determined outsider, seeks justice. Teaming up with Dr. Jacob Sandys, a disgraced ex-soldier with a dark past, Dora follows a trail of cryptic clues leading them into the underbelly of England’s most feared societies.
As Dora and Jacob close in on the truth, they uncover a deadly conspiracy, standing between the Hellfire Club and the powerful Illuminati. Their investigation draws them into grave danger and undeniable passion, with every discovery pulling them deeper.
Will they survive unmasking the killer—or fall victim to the darkness themselves?
