This is the fourth book in the Galactic Warriors series written by James Floyd. This book continues the story of the teenage warriors as their allegiance with the former enemies, the Neptonians, continues to grow. In the third installment, Czar Xavier attempted to invade the Zartonian galaxy in an attempt to defeat and enslave the entire Hedera Solar System in a feeble attempt to seek revenge on the Gemminites that exiled him. But the unity and alliance of the Nebulans and Neptonians proved too much as they were able to drive Xavier back to the Baltic Region. In this installment, we will learn that Czar Xavier and his robotic empire aren't quite finished. After his last defeat, his desire for domination has only increased, especially where Queen Alexandria and the Galactic Warriors are concerned. But this time is all or nothing. Can the Warriors do it one more time?
