Silver Tation is one of the not-so-idle rich of Imbrium, Luna. He is also a con artist and thief, under the alias Quicksilver. After honing his skills for three years on the Moon, he's ready to go to Titan and exact some personal revenge. But his last mark in Imbrium has the poor timing to be murdered, and Sil appears to be the suspect of choice. Still, there's not much the law can do while he's on Titan, so he goes ahead with his plan, enlisting the help of a cyborg gem grader who only wants her freedom.
