The kingdom's legendary weapons answer only to royal blood. The last of the line is a mechanic in a town far from the throne.

Rowe Thackeray is the kingdom's only heir and nobody ever told him. He fixes engines in Basincall and reads a machine's failures through his bare hands. Then the king is assassinated, and Natet's knives turn toward the man standing between the empire and the crown.

Kiana delivers the truth along with orders to bury him in a safehouse. Instead, he signs with the Adventurers' Guild and stays moving, running convoy escorts and monster hunts down the Southern Loop. She rides along to keep him breathing and finds the asset she was sent to manage keeps acting like a man worth following. So does Dru, the oni bodyguard hired to do his bleeding for him. She jokes through every fight, hits harder than anything on the Loop, and would take a killing blow before she lets one land on the man she calls hers.

The road has plans of its own. Guild jobs land the team at sealed dungeons where royal weapons sleep, weapons only Rowe can claim, and every draw drains the man holding it. While he grows stronger, Natet's soldiers tighten around Basincall and the family he left behind.

Fast action, explicit heat, light LitRPG progression, and two extraordinary women who choose the mechanic long before anyone calls him a king.
