The Sign of The Blood

"Exciting and original," SJA Turney, author of Caligula.
Cool mist settles over the legion advancing toward the Persian army. Constantine, the son of an emperor, the Roman officer leading the attack, tells his men to halt - something is wrong.
Before long, the battle rages. He frees a slave named Juliana. She is half Persian and half Roman. As they are pursued to Britannia over land and sea, he learns that she can see the future - his future.
It is 306A.D., long before Constantine the Great converted to Christianity and became the first Christian emperor.
To ensure he survives, he must eliminate his enemies. But who must die first? The priestess, Sybellina, who joined them in Rome and practices dark and seductive magic? Or the brutal legion commanders who surround his father? Or, as Juliana suspects, are those who want him dead even closer?
A gripping historical novel about Constantine's bloody rise to power, the woman who helped him, and the real reason he supported a persecuted Christian minority, a decision which changed the world into the one we know.
