Description: On the Twin World planets, Plenipotentiary Gregor is determined to serve his government--even if it means executing innocent Huvean hostages, invaders from another planet--and even though Gregor's own granddaughter, Luon, is in love with a Huvean. But now the Berserkers are threatening the Twin Worlds, capturing the planets' president and reprogramming his brain to suit their violent agenda. And only the Huveans, in a desperate reprieve, can save the Twin Worlds' populace from annihilation.
