A thousand years have passed since a dragon has been seen in the world. Science and technology have replaced magic, which has dwindled until it has become little more than an element of myth and legend. There are those who still have dragon blood flowing through their veins, distant descendants of the mighty creatures of old. These rare humans have the power to cast magic, the power to heal, and the power to craft alchemical weapons capable of starting wars...or ending them.

As a cartography student, Jak has always dreamed of finding the lost dragon gate and exploring and mapping distant worlds. Developing magical powers and becoming a powerful wizard? Not a chance. But when he and his archaeologist mother unearth the gate, they attract the attention of the very wizards they sought to avoid. Even more troubling, Jak starts developing magical powers of his own, powers that could rival those of the great rulers.

Imperial law enforcer Amaranthe Lokdon is good at her job: She can deter thieves and pacify thugs, if not with a blade, then by toppling an eight-foot pile of coffee canisters onto their heads. But when ravaged bodies show up on the waterfront, an arson covers up human sacrifices, and a powerful business coalition plots to kill the emperor, she feels a tad overwhelmed. Worse, Sicarius, the empire's most notorious assassin, is in town. He's tied in with the chaos somehow, but Amaranthe would be a fool to cross his path. Unfortunately, her superiors order her to hunt him down.

Arwen Forester may be a socially awkward introvert, but she’s an expert tracker, archer, and forager who has a pickling recipe for every vegetable in the garden. Unfortunately, none of these skills earn her a lot of money. And when the taxes go up on her father’s farm, she’s not sure how to help him keep the property. Then someone offers her a lucrative new gig: Hunt down a haughty half-dragon criminal with the power to incinerate those who irritate him.

An enforcer wanted dead for crimes she didn’t commit.... An assassin wanted dead for crimes he did commit.... Normally, they would be enemies, but they both seek the same thing: exoneration. Unfortunately, a nefarious underground organization is attempting to kill the one man who could grant it to them - the emperor. If they want to win their freedom, they’ll have to battle powerful wizards, outscheme master schemers, and defeat bloodthirsty monsters, all while dodging friendly fire and evading the law. Exoneration isn’t easy.
