ARKANE Thrillers Series

When fire falls from the heavens… will the whole world burn?   Dr. Morgan Sierra, an Oxford University psychologist with a deadly past, doesn't know the answer to that question — and doesn't care. All she knows is that her sister and niece have been abducted, held hostage for the stone pendants that Morgan and her sister wear: two of twelve relics once owned by the original Apostles.   Forged in fire and wind, drowned in the blood of martyrs, the twelve Pentecost stones have been kept secret for two thousand years. But now the Keepers of the stones are being murdered, and the relics stolen by Thanatos, a shadowy group dedicated to remaking the world into a living Hell.   The authorities are clueless; the world lies helpless. And Thanatos grows more powerful with each stone they take.   Enter Jake Timber — agent of ARKANE, the British agency tasked with investigating the supernatural. Jake knows some of the secrets Morgan needs to save her family, but can't stop Thanatos without her help. Only together can they stop Thanatos before the stones are captured, before Morgan's family is murdered, and before the world is changed forever.   From flooded ruins in Italy, to religious sites in Israel, to the far reaches of Iran and Tunisia, Morgan and Jake must race across the world to find the stones before Thanatos gathers the relics and uses their power to turn Earth into a living Hell.   But every step they take brings Morgan and Jake closer to the end. To the knife edge between salvation and madness. To the moment when Morgan will have to decide whether she will save her family… or save the world.   Time is running out. Thanatos draws near. And the day of Pentecost is at hand.   Stone of Fire is the first book in the ARKANE series by New York Times and USA Today bestselling author J.F. Penn.

It is the seat of judgment. The pinnacle of holiness. It is the Ark of the Covenant… and it's the most dangerous weapon in existence.   A group of fanatics wearing masks of Egypt's gods slaughter the curator of Cairo's most famous museum. A cleaner in Washington, DC, discovers a decapitated head on top of a replica of the Ark of the Covenant. And someone is sharing videos of the deaths with extremists all over the world.    It's a job too big — and too strange — for the normal authorities, but it's right up the alley of ARKANE, the British agency tasked with investigating mysteries on the edge of the supernatural.    Normally ARKANE would send its best agents: Morgan Sierra, ex-Israeli military and professor of psychology and religion; and Jake Timber, a man as mysterious as he is dangerous.    But Jake is in a coma, nearly killed on a previous mission — so Morgan will have to go it alone. Because the death toll is rising, and there's no time to wait.   In over her head, in constant danger. Pursued by vicious mercenaries bent on revenge, hunted by assassins willing to do anything for their cause. But Morgan can't stop, because the Ark of the Covenant is the prize, and it may be more than a simple religious artifact.    It may be the secret to ancient alchemy, and the unlocking of a scientific breakthrough that could save the world… or end it.   A mix of Raiders of the Lost Ark, James Bond, and The Da Vinci Code, Ark of Blood is a mesmerizing adventure by New York Times and USA Today bestselling author J.F. Penn. Grab your copy today, and get lost in the world of ARKANE!
