Deep in the icy black of the North Atlantic, a state-of-the-art submersible makes a chilling discovery—a metallic object slicing through the water with impossible speed and precision. Moments later, systems fail, lights die, and terror takes hold. On Mars, a European rover transmits the image of a stone—etched with unknown symbols—just before vanishing from the data grid. Entire neighborhoods in Nevada disappear without a trace. And in the French Alps, a champion cyclist vanishes mid-race, his GPS pinging him thousands of miles away—then gone.

Colton Beck has six months to live. He works for the Angor near Los Angeles, aware that any day could be his last. The Angor arrived 20 years ago, resolved to help mankind survive, but not everyone believes their motives are honorable. When the Angor offer humanity a colony world, Colton is determined to see another planet before his final breath. He’s been diagnosed with Xeno, a rare disorder that surfaced with the Angor’s arrival, but he won’t let this stop him.

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.

Your First AI Blueprint cuts through the chaos and overwhelm. It gives you a simple, beginner-friendly guide to understanding AI, talking to it effectively, and building real systems that save time, reduce stress, and boost your value at work — exactly the roadmap people wish they had when they first started. You don’t need to be technical. You don’t need coding. You don’t need years of experience. You just need a clear pathway, one that shows you exactly how to think, communicate, and build with AI in a way that feels natural and immediately useful.

Die postapokalyptische Welt war noch nie gefährlicher. Während Lance, Joy und ihre zerzauste Gruppe von Überlebenden müde durch eine verwüstete amerikanische Nation ziehen und gegen Banden von Kriminellen kämpfen, die ihnen alles nehmen würden, was sie besitzen, entdecken sie, dass die größte Bedrohung noch vor ihnen liegt.

Aliens ripped a hole above Earth, arriving with a massive space station. I sorta figured we'd be enslaved to fight in their wars or exterminated for our resources. Nope. The hip-high Iglax were merchants with ugly squished faces and thick blue fur. While they weren't much to look at, they sure did have some wonderous technology. Humanity bent over backwards to appease our new merchant overlords. The boorish aliens wanted cheap labor for precious metals, and honestly, I didn't blame anyone for their hunger to be among the stars.

Where did mankind really come from? Why are we here? We can't understand the past until we embrace the future. These critical mysteries take center stage as Earth emerges into a galactic society that is far more perilous than anyone could have imagined. Our history is far more complicated than we could have known. Can a few brilliant minds find a way out for Earth?

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.

The Mirror Lancer Alyiakal has been ordered to Mirror Lancer Headquarters and promoted to Subcommander, ostensibly to advise the high command on tactics—except Alyiakal's successful military campaigns have removed most external threats to the Empire of Light.

In a near-future world where technology and humanity converge, "Singularity Titanium" tells the story of Kron, the first humanoid robot designed with advanced artificial intelligence and emotional understanding.

When ninety-percent of the Universe's population suddenly turned into monsters, Leo has no time to grieve. He must push forward and find what is left of his family. If that means sacrificing what remains of his humanity and embracing his new reality where a mysterious System is his only true ally, then so be it. After all, in a world where almost everything wants to kill him, he has to decide if he can do what it takes. Adapt or Die. Kill or be killed.

Abigail Swish's life is nothing to brag about: gang-ridden city, orphanage style accommodations, and a matron who's kinda on the evil side. Not that she has to worry about that for much longer. She'll turn 18 soon, and then it's goodbye compound, hello dangerous streets of New York City. Of course, as her luck would have it, she doesn't make it to 18 before her world is turned upside down. One ambushed meeting with an accent-bearing, sword-wielding stranger, and suddenly her entire life as she knows it is a lie.

Earth has united under the banner of the Republic. Humanity's brightest minds have deciphered the secrets of the alien technology and have begun to reverse engineer it. An elder race takes notice of humanity's strides and intervenes. Humanity is brought into the fold of a galactic alliance and learns they are not alone in their war against the insidious Zodark empire. Humans now fight alongside friendly alien races to end the bondages of slavery.

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.

A colony survives among the icy rings of a planet, hiding from alien robots determined to destroy them … at a remote site on the edge of the Arctic Circle, a group of scientists, engineers, and physicians gather to gamble humanity’s future on one last-ditch experiment … a man who can’t feel pain has been bioengineered to be a killing machine, but he refuses to give in to his fate … a man is contacted by three future versions of himself, each trying to save their world from destruction.

Is cosleeping safe? How important is breastfeeding? Are food allergies preventable? Should we be worried about the aluminum in vaccines? Searching for answers to these tough parenting questions can yield a deluge of conflicting advice. In this revised and expanded edition of The Science of Mom, Alice Callahan, a science writer whose work appears in the New York Times and the Washington Post, recognizes that families must make their own decisions and gives parents the tools to evaluate the evidence for themselves.

It seems like every time a new mother turns on her computer, radio, or television she is greeted with news of yet another scientific study about infancy. Ignoring good information isn't the right course, but just how does one tell the difference between solid studies, preliminary results, and snake oil? In this friendly guide through the science of infancy, Science of Mom blogger and PhD scientist Alice Callahan explains how nonscientist mothers can learn the difference between hype and evidence.
