The wait for another sequel to the Synchronicity War/Retro War is over! Twenty-one years have passed since the end of the wars against the Insectoids and the rogue AI Machineships. A new generation of Shilohs has joined the Space Force, much to the joy of the AIs that still revere the memory of The Cag, Victor Shiloh. And, once again, humanity is in mortal danger. The temporal backlash from multiple time jumps that the Friendlies had warned against is making itself felt with a vengeance. Can humans and their loyal AI allies find a way to undo their meddling with time? Changing the past without resorting to time travel will be but half the battle. Victor Shiloh and his AI allies, Iceman, Valkyrie, Casanova, and the others, will have to find a military solution to the nightmarish Insectoid peril. There can be no time travel shortcuts this time. It will be a battle to the death, with the fate of all life in the galaxy hanging in the balance.
