Unfortunately Earth was in the Alien bug region. Things went along fine for a while until 24 Alien bug starships showed up. The Alien bug queen took over the Earth and stopped the wars and got people to live in peace. The Queen put devices at both poles to melt the ice caps so there would be more land to settle on. As the oceans rose, the water forced the people to move inland and build new houses.

Things worked out fine until a large alien bug fleet arrived with an Alien Bug Queen that wanted to kill off the entire human race and take over the planet. Captain Josh Miller decided he had better join with the 24 Alien bug starships so the Earth would be saved. This novel was many twists and turns and plenty of adventure.
