In a desperate bid to revive his spy service, Marcus Gregorianus Numidianus vows to thwart a coup staged by diehard Constantine loyalists against the Valentinian brothers' new regime. But Marcus has underestimated the rebels' clever planning. He arrives in Constantinople too late to save Emperor Valens' throne. Now trapped in the East as a double agent with only a deaf brigand and an escaped slave woman for allies, can the wounded freedman survive to become Magister Agentium in Rebus, spymaster to the new dynasty? Packed with action and intrigue, the Embers of Empire series now takes the reader into the Valentinian Dynasty of the 4th century Late Roman Empire to delight fans of Bernard Cornwell, Steven Saylor, and Robert Harris.
