the Halls of Shadow King: Britannia Calls

In the third century Roman Empire, the Shadow King's network of hidden believers is quietly reshaping the world. But a new threat has awakened in the far north.An ancient dragon stirs beneath the mountains of Britannia - older than Rome, older than memory - and the young communities of The Way taking root across the island are directly in its path.Amal, the man some call the Shadow King, assembles a team unlike any he has led before: a legendary, long-lived Celtic warrior, a former temple priestess whose years on the wrong side of spiritual power may prove their greatest weapon, a young woman haunted by visions she can barely endure. They sail from Antioch to the edge of the known world, through enemy-held seas and fog-wrapped moors, toward a confrontation that prophecy says one of them will not survive.Britannia Calls is historical fiction with teeth - rigorous in its third-century detail, unsparing about the cost of courage, and shaped around a question the series has always asked: what does a person owe to something larger than themselves?For readers who want their history gritty, their faith tested under fire, and their heroes genuinely at risk.
