Triple Détente: Piers Anthony

Earth's invincible space fleet has occupied the monsters' worlds! Earth's mighty space force has seized the aliens' home planet! Earth's triumphant space warriors have captured the enemy system! But then...why is Earth suffering so beneath the tread of those heartless conquerors from the stars? Earth and Kazo have created a unique peace. Kazo administers Earth, and Earth controls Kazo. Nothing is really complicated until both humans and Kazos discover the existence of a third intelligent race in the galaxy and try to bring them into the newly developing peace.
