Alien attacks on Earth have failed, defeated by human advances in physics and telepathy. But a Centauri fleet near the Sol system reacts with fury, determined to find out why a routine Sentinel Suppression mission failed, and capture and eviscerate the captain who betrayed them. Two autistic boys, Robby and Luca, search for their lost parents-lost in the dystopia created by the alien attacks. But the rogue alien captain, Cap, is thrilled by the emergence of the boys' telepathy mutation and helps them in their quest. Scott Anderson, Robby's physicist brother, joins the Space Force weapons development team to defend against the approaching alien fleet. But man's technology that harnesses the energy of primordial black holes is primitive compared to the Centauri fleet's weapons.Centauri warships launch kinetic energy projectiles and planet killers, forcing a frantic search for weapons to defend Earth. Scott's and Robby's telepathic collaboration with the alien captain is the key to devising weapons effective against the Centauris-the only hope for man's survival.
