Aemilius is barely a man when a harpy out of myth knocks him from his horse. He is saved - and recruited - by the Hidden Legion, a secretive order of soldiers, magicians, and rogues. A darkness is growing across the Empire, and someone is setting traps for the Legion themselves. Aemilius and his new comrades must find an unknown enemy?

Paperback edition of the bold new historical fantasy of a secret order of Roman monster-hunters.

We do not exist. Our task is to hunt monsters that threaten the Empire. We are the Hidden Legion.

Aemilius thought he would die heroically in battle like his forefathers, not gutted by a creature out of myth on a lonely mountain pass. But death came for him on terrible wings and claws… and at the last moment, he was saved.

And now, somehow, he’s the newest member of the so-called “Hidden Legion,” tagging along with a squabbling crew of heathens, vagabonds, killers, wizards, disgraced nobles and former soldiers, hunting monsters to keep the world safe from chaos.

It is the twentieth year of the reign of Emperor Tiberius Caesar Augustus, and a darkness is growing across the Empire. And an unknown enemy is setting traps for the Legion itself…
