While on a well-deserved leave in an orbital city, Connor Duffy meets a mysterious Gelt woman with a proposition. She has a device that can transport a ship instantly across light-years. All he has to do is free her from an indenture contract.

But her employer does not want to let her or her prize go. And the aliens who invented the device want it back. Time is running out. Because while Duffy learns everything this device can do, the Compact of Humanity is tearing itself apart.
