The Devil's Fire — Stuart Daly

To prevent a world-shattering prophecy from coming to life, Jakob and his companions must form a truce with an order of the English witch hunters to battle demonic soldiers known as the Sons of Cain

Summoning the Prince of Darkness is only made possible should the Codex Gigas, a medieval bible, contain the spell. So when the medieval bible is stolen by demonic soldiers known as the Sons of Cain, Jakob and his companions form an alliance with an order of English witch hunters and race to London to prevent a horrific prophecy from being fulfilled. Whether battling his way into the prisons of Rotterdam or crossing blades with the Sons of Cain during the Great Fire of London, this will be Jakob's most perilous mission yet, including a nightmarish prison, a charismatic prince, a graveyard of unspeakable horrors, and a race to the death.
