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.
