Three suns in the sky. Four emperors at war. One God remains.
Gaul, AD 310. The sky splits open—and an empire follows.
Four men claim the purple, their armies marching toward civil war. And above a frozen plain in Gaul, ten thousand soldiers watch three suns burn in the sky.
The emperor asks what it means. His Christian tutor doesn't answer, and he will spend the rest of his life atoning for that silence.
Told by Lactantius—court scholar, reluctant advisor, secret chronicler—In This Sign follows Constantine through the bloodiest gamble in Roman history: a march over the Alps with forty thousand men against an enemy of one hundred thousand. Sieges and betrayals. A barbarian kingmaker with blood on his conscience. A teenage empress playing a longer game than any general. A dead woman who will not stay buried. And a drunken midnight descent into a crypt beneath the palace, where a necromancer speaks with a voice the emperor knows all too well.
From the blizzard of Mont Cenis to the slaughter at Turin, from a duel that decides Italy to the bridge that stands between him and Rome, Constantine is vexed by a question no oracle can answer: which god is on his side?
The answer will remake the world.
In This Sign is the second book of the Constantine the Great trilogy, following Son of Helena. Meticulously researched and unflinchingly told, it's historical fiction for readers of Conn Iggulden, Simon Scarrow, and Steven Saylor.
