Jeff Dolan always wanted to be an astronaut. After helping a private space company build a ship that can travel to Saturn's largest moon in five months, he gets his chance. Shortly after launch, a devastating malfunction forces Jeff and the crew to make a choice: continue to Titan or go back home. As the truth about their mission unravels, one thing is clear: Someone on Earth knew about the system flaw and covered it up. Yet surviving the journey isn't the crew's only concern. Even if they make it to Titan, they will face another problem: Something is already there.

In this thrilling second book of the Earthborn trilogy, Lucas and Asha have survived the decimation of Earth at the hands of the invading Xalans and seek safe haven with their enemy's true foes, the Sorans. They find a lush planet inhabited by a civilization far more advanced than their own, waging a seemingly endless war against a constantly evolving enemy. The Sorans call the pair of them the "Earthborn", and they're welcomed as heroes, almost as gods.

Twenty-seven years later, the Firstborn are back. This time, they have sent a "quantum bomb" speeding toward Earth, a device that human scientists can barely comprehend, let alone stop or destroy. But when shocking new insights emerge about the nature of the Firstborn and their plans, an unexpected ally appears from light-years away.

This book is about the heart of religious experience, namely Enlightenment (which is finding the truth concerning oneself), and about science (which is finding the truth concerning other things), and about the relationship between them. It claims that Enlightenment is more truly scientific than science itself; and that, without Enlightenment, science is only half the story and therefore full of contradictions, of insoluble problems both theoretical and practical.

It was Chris Alan's very first day of seventh grade. That's hard. It's bad. No child should be asked to do such an awful thing. Humiliation, embarrassment, and social isolation await him. Then, of all days, the aliens decide to launch their conquest of Earth. So, along with Chris's preteen angst, he gets aerial bombardment, and then vicious insectile aliens pile out of their ships and start killing humans in earnest. What a rotten first day of class!

The aliens tested humans on an individual basis for miner rentals. Do well on your pilot test, get a spaceship, sign up with a corp, and you can mine the belt. For a puddle-jumper pilot like me, yeah, I was so interested I became obsessed. When I finally tested, I performed above and beyond, being offered a contract for some better than a miner - Earth's First Starfighter.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

I was in my garage, when the space elves addressed the whole world. They didn't call themselves space elves, of course, but most humans struggled to pronounce Khjurhnalva. They had a message for us: Forces that had eradicated their species' males were heading for Earth. The space elves offered us access to the System, as cooperation was vital to the survival of both our species. I, Mathew, know all of the above is bullshit. I saw the truth with my own eyes, heard it from their beautiful, deceitful mouths. No one believes me, though. A planet-wide, survival reality show? Ridiculous.
