Crusader from Mars #1

Convicted of a crime on Mars, Tarka and Zira are offered a chance at redemption: travel to Earth and stop the small nation of Herzegovina from deploying a devastating bacteriological bomb against the United States. Facing bureaucratic resistance and the clock ticking toward attack, the pair must find a way to prevent catastrophe before it's too late.

Exiled Martians Tarka and Zira must stop a sabotaged plot to destroy America's grain supply before cosmic-powered weapons can save the day. Racing against a manufactured famine orchestrated by enemy agents, the pair from an enlightened planet uncover a scheme to cripple the nation—and Tarka takes a dangerous gamble in Earth's atmosphere to turn the tide. It's a high-stakes crusade that will test whether two off-world crusaders can master Earth's science faster than their enemies can strike.

In 2042, nuclear physicist Jacob Dis discovers rays that can neutralize atomic weapons—and when the world ignores his warnings, he uses them to shut down all nuclear fission on Earth, including the sun itself. Facing global panic and the collapse of civilization, Dis forces world leaders to choose between their individual nations and unified peace, but his greatest challenge may come from an unexpected source close to home.

In 1952, as Cold War tensions threaten nuclear annihilation, Captain Basil Steel and his wife Vicki lead a handful of volunteers aboard the Solar Queen, Dr. Jan Morphy's experimental rocket, in search of Planet X—a distant world where humanity might start anew. After weeks of drifting through space on failing fuel and dwindling supplies, the crew encounters a gravitational pull that draws them to an unknown planet, where they discover the shocking ruins of a familiar civilization. What they uncover in those ruins will force them to reckon with the true cost of their journey and the fate Dr. Morphy warned them about.

Professor Birdbrain has finally perfected his automatic exterminator, and he's eager to demonstrate this remarkable bug-killer to Mr. Spraygun, the businessman who's been funding his work for three years. When the scientist walks through his invention's elaborate process—involving insecticide, gunpowder, an electrical socket, and a trigger—Mr. Spraygun quickly discovers that the "remarkable" machine might not be quite as revolutionary as promised.
