Ardent Violet and the Infinite Eye - Starmetal Symphony, Book 2

In this new wide-screen space opera, humanity has met its match. An alien race of enormous robotic AI have destroyed most of humanity's outposts. But, on the eve of the Earth's destruction, a musician made one last desperate attempt to reach out and convince one of humanity's enemies to switch sides. Now, earth just might have a chance to survive... A ragtag band of misfits is all that stands in the way between an army of giant mechas and humanity's total destruction in the second book of this big-hearted, technicolor space opera trilogy by one of the most exciting voices in science fiction, Alex White.
Ultra-glam enby pop star Ardent Violet thought they could catch a break and enjoy some time with their new boyfriend August Kitko after defeating the giant mechas hellbent on humanity's destruction. However, Ardent didn't count on their mecha allies summoning a host of extraterrestrials to defend Earth. Between the diplomatic entanglements of the newly-arrived alien Coalition, and a mysterious all-powerful AI establishing a base within their solar system, there's no rest for the wicked.
When August makes a discovery that could turn the tide of the war, Ardent Violet finds they are back in the spotlight for an encore!
