For years Gregory Roarke and his Kadolian partner Selene have worked for the ultra-secret Icarus Group, hunting for the mysterious Icari teleportation portals so valued by the Commonwealth. But their job has now come to a wrenching end. The two of them are fugitives, sought by the Commonwealth, the rival Patth, and the remnant of the ancient Ammei who once controlled the portals and who hunger for a return to those days of glory. All three groups want Selene and her unique ability to understand and deal with Icari technology. Or is it unique? In the shadow of an Ammei stronghold they stumble across an unfamiliar and badly confused alien named Bubloo who has the same ultrasensitive sense of smell as Selene and her fellow Kadolians. If the Ammei get hold of him, can they achieve their goal of domination without Selene? Roarke doesn’t know. But he doesn’t dare take that chance. Things are looking grim, with multiple puzzles and questions intertwined around Bubloo and the portals, and the future of the Spiral hanging in the balance. And then, the Patth assassination squad arrives . . .
