The first novel in Simon Scarrow's bestselling Roman series. It is 42 AD, and Quintus Licinius Cato has just arrived in Germany as a new recruit to the Second Legion, the toughest in the Roman army.

25 BC. Titus Cervianus is no ordinary soldier. A former surgeon from the city of Ancyra, he's now a capsarius—a combat medic. Cervianus is a pragmatist, a scientist and truly unpopular with his legion. The Twenty Second Deiotariana have been sent to deal with uprisings and chaos in Egypt. Yet the Twenty Second is no ordinary legion either. Founded as the private royal army of one of Rome's most devoted allies, the king of Galatia, their ways are not the same as the other legions, a factor that sets them apart and causes friction with their fellow soldiers.

What seems a straightforward, if terrifying, assignment soon descends into Machiavellian treachery and peril as everything in which young Rufinus trusts and believes is called into question....
