An Imperial captain must confront an ancient treachery.

Lucius Varro, a captain in the Fourth Army, is about to have the worst day of his life. Wounded, poisoned in battle and fearing for his life, he stumbles upon a plot that reaches deep into the past and the roots of everything in which he believes.

Accompanied by a young engineer from his unit and the daughter of his commander in chief, he begins to unpeel layers of treachery and murder that threaten not only himself, but the people that he loves.

Varro is determined to find his betrayer, but the poison is incurable, and there isn't much time left...

Ironroot is set twenty years after the events of the first Tales of the Empire novel, Interregnum. Inspired by Roman history, this is an evocative and action-packed tale of treason and revenge, sure to delight fans of Conn Iggulden, Bernard Cornwell and Simon Scarrow.
