Everyone loves a complex science-fiction adventure. The struggle for survival and control takes a new turn in this third book in the Clash of the Aliens series. The previous novel, Stranger, left the human race devastated by an apocalypse of their own making. They are picking up the pieces of their civilization and preparing for an outside threat—the alien race of Qu’uda. As Blue Gem unfolds, the humans do not know that a third alien species, the Hoo-Lii, are on their way to Earth. The strange, exotic Hoo-Lii Hive-Mother, Suh-Joh, seeks a new world because the ruling priest class has sentenced her to death. She sends her counselor to investigate Earth as a new home. When the Hoo-Lii ship arrives, it suffers major damage at the hands of the Qu’uda. The humans set out to help the Hoo-Lii with a gift of water. As the old saying goes, “No good deed goes unpunished.” This benevolent gesture may have inadvertently sold out the human race. Will this gift of water seal Earth’s fate? Find out—get it now. "A solid post-apocalypse/space-war action tale for sci-fi fans”—Kirkus
