Roman conspiracy. A deadly legacy.

Banished from Rome, engineer Agrippa Cicero uncovers a vast network of volcanic tunnels running beneath the empire: hidden roads of fire and stone capable of moving gold, armies, and secrets beyond imperial control.

When Mount Vesuvius stirs and political tides turn deadly, Agrippa is pulled back into Rome's shadow. As cities burn and loyalties shatter, he is forced to hide a final secret deep underground: a map and a legacy meant to die with him.

It doesn't.

Nearly two thousand years later, the tunnels will be found again. And whoever controls them will control what survives.
