For spoiled young aristocrat Colin Harwood, the port city of Casmile is a buffet of easy pleasures. But when he steps into a pub brawl to help a dangerously outnumbered young man, he is drawn into the seedy underbelly of the city the young man calls home.

Gabriel is a cutpurse and a knife for hire, practically an urban legend. His vision of Casmile is touched by a strange combination of faith and madness, driven by fairytale logic and a capacity for love that he often must suppress to survive. He's always worked alone, but when a dashing dragon who calls himself Colin saves him in a bar fight, he pulls Colin into his world.

Gabriel's city is nothing like the refined, socialite existence that bored Colin senseless. Colin finds adventure and excitement there—and maybe even love. But with his layers of finery stripped away, nothing remains to protect him from poverty or danger—except Gabriel. So he must choose: go back to the civilized young man he once was, or fly free as Gabriel's dragon.
