Across the Galactic Gulf lies Quarus, a world so strange that decades of human diplomatic effort have failed. With the quarians about to close their borders, there is one last hope to save the relationship: Alex von Strada and the Fourth Fleet Irregulars. This is a mission which will take them further than the Fourth has ever been. They have no plan, no idea what will happen. All they can do is embrace the chaos that is exodiplomacy... oh, and get naked.
