The realms of God

"The Ark of the Covenant is in flight, spirited out of Egypt to Petra, the legendary, rose-red city of stone. But dark forces are in pursuit. Three demons, inadvertently unleashed by Juba of Numidia and the daughter of Cleopatra, are in league with Tiberius, son and heir of Augustus Caesar. They've seized two of the fabled Shards of Heaven, and are desperately hunting the rest. Through war and assassination, from Rome to the fabled Temple Mount of Jerusalem and on to the very gates of Heaven itself, the forces of good and evil will collide in a climactic battle that threatens the very fabric of Creation. The Realms of God is the third book in a triptych of historical fantasy that continues the story begun in The Shards of Heaven and The Gates of Hell. Michael Livingston, a well-known medieval scholar, has crafted a thrilling conclusion" --
