Generations ago, Convoy Seven and I.C.C. left Earth on a mission that would take them far beyond the solar system. Launched by the Planet United Consortium, a global group formed to pursue cooperative Earth-wide interests in deep space, nine ships headed into the unknown to explore a distant star called LQ Pyx. Eons later, the convoy has returned to LQ Pyx to begin work on the Web, the alien megastructure that covers the star. Is it a Dyson Sphere, designed to power a civilization as everyone believes--or something far more sinister? Meanwhile, Planet United's littlest convoy, long thought to be lost, reemerges in a different sector of deep space. What they discover holds the answers to unlocking the Web's greater purpose. Each convoy possesses a piece of the Web's puzzle . . . but they may not be able to bring those pieces together and uncover the structure's true nature before it's too late.
