In the fourth book of the Extinction Wars series, Abaddon commands a Karg-Jelk Super Fleet bent on annihilating humanity. He's the galaxy's most ruthless strategist wielding superior technology. That includes the perfect raid-ships, able to teleport anywhere at will. Humanity has Commander Creed, and he has his Assault Troopers. He's going to take the fight to the enemy. He's buying time, learning secrets and setting up for the greatest space battle in the Orion Arm.

Five years ago, we won our first galactic war. We defeated the scum, a race of alien centipedes. But the marauders are stronger, smarter, and crueler by far. And they will show us no mercy. Marco Emery, hero of the last war, struggles today as a civilian. Shell shock cripples him. Nightmares haunt him. Yet now he must become a soldier again. Now his old platoon must reunite. Together, they must defeat the greatest threat Earth has ever known. Or humanity will fall.

Lord Anakreon, Warden of the First Circle, has lost a weapon. Not just any weapon; the Planet Forge is an ancient alien artefact with the power to create worlds…or to end them.

Poised to reconquer humanity's home, Captain Absen and Conquest are confronted with a new enemy that upsets the balance of power and changes everything EarthFleet expected. Their struggle to free Earth becomes instead a desperate battle for sheer survival as they contemplate the unthinkable: total annihilation.

Tragedy and triumph war for supremacy, but the victory will be short-lived. Because the terrifying race known as the Siszar—once humanity’s greatest foe—have requested our aid. Not even they are immune to the devastation caused by the Black Ships. Their homeworld has been destroyed. Kreon, Tristan and Kyra must fight their way deep into alien territory, to forge an alliance with a creature half as old as time. Only then can they have any hope of defeating the Black Ships. But not everyone wants them to succeed.

One world at a time, the entities known as Black Ships are wiping out all sentient life. There is no way to stop them. No way to find them, even...because no one has ever survived an encounter. And yet, the hologram of a long-dead Warden points towards a glimmer of hope; an ancient Oracle hidden deep in enemy territory. Could this be the key to unravelling the mystery?

It’s more than just a career - it’s a sacred calling…but it comes with a very short life expectancy. Lord Kreon, Warden of the First Circle, has a problem: he’s been forced to kill another apprentice, and he’s rapidly running out of candidates. In fact, there is precisely one left….

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

200 years ago it devoured Earth. 20 years ago it devoured Gilgamesh. 2 weeks ago it entered our dreams. Al isn’t just a spy, he’s one of the best covert agents alive. At least, he was before everyone in the system started dreaming about him. Now his cover’s blown and he’s out of his depth, scrambling for answers to a mystery humanity has never been able to solve. The Goo. The great cosmic, planet-eating substance that swallowed whole systems.

Against all odds, the Ark and her 30,000 survivors have reached Tau Ceti G to begin the long, arduous task of rebuilding human civilization. Meanwhile, on the other side of the world, Tau Ceti G's natives, the g'tel, are coming to grips with the sudden appearance of what many believe are their long-lost gods.

What do you know about planet Earth? Give curious kids a first look into space.

The marauders, terrors from deep space, hit us hard. Our starships shattered. Our armies collapsed. Our cities crumbled. As Earth smolders, the marauders imprison us in camps. They farm us like cattle. They torture us for sport. Earth weeps. But there is hope. The Ghost Fleet, an ancient alien armada, might still exist in deep space. In a single starship, Sergeant Marco Emery and his friends seek this mythical fleet. They must find it. They must return with its might. Or the marauders will kill us all.

As part of the fabled S4, Lance Warder is stationed on Mars when first contact is made. The Galio have arrived. Lance is selected to act as diplomatic security and all appears to be going well between the two species until a radical group known only as the Veles rear its ugly head and decide conflict must follow.

In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?

This audiobook explores how the discoveries within the Solar System and of exoplanets far beyond it come together to help us understand the habitability of Earth, and how these findings guide the search for exoplanets that could support life. The author highlights how, within two decades of the discovery of the first planets outside the Solar System in the 1990s, scientists concluded that planets are so common that most stars are orbited by them. The lives of exoplanets and their stars are inextricably interwoven.

In Earth-Shattering, astronomy writer Bob Berman guides us through an epic, all-inclusive investigation into these instances of violence both mammoth and microscopic. From the sudden creation of dazzling "new stars" to the furiously explosive birth of our moon, from the uncomfortable truth about ultra-high-energy cosmic rays bombarding us to the incredible ways in which humanity has harnessed cataclysmic energy for its gain, Berman masterfully synthesizes some of our worst fears into an astonishing portrait of the universe.

On August 21, 2017, more than 10 million Americans will experience an awe-inspiring phenomenon: the first total eclipse of the sun in America in almost 40 years. In Sun Moon Earth, astronomer Tyler Nordgren illustrates how this most seemingly unnatural of natural phenomena was transformed from a fearsome omen to a tourist attraction. From the astrologers of ancient China and Babylon to the high priests of the Maya, Sun Moon Earth takes us around the world to show how different cultures interpreted these dramatic events.

After the dramatic and unexpected turn of events at the end of the first book, planet Earth is left with several factions trying to resolve the situation. The new president of the USA is trying to secure his hold on power, while a new group - who have named themselves Free America - is taking steps to overthrow what it considers an illegitimate regime.

In a desperate battle, Earth has temporarily freed itself from the clutches of the deadly Trellixian Empire. Billions are dead and it's only a matter of time before the enemy return. Seeking aid against the Trellixians, two exploration ships are sent out to search the galaxy for allies. If they fail, then the human race is doomed.

The Trellixian Empire was constantly expanding, seeking new worlds for its ever-increasing population. If worlds were discovered with existing sentient populations, they were cleansed to make room for colonization. Hundreds of budding civilizations had been eliminated by Trellixian battle fleets. On Earth, years in the past, a scout ship fleeing from the Trellixians crashed. Scientists investigating the wreckage discovered what the Trellixians had done to the world the scout ship escaped from. They also discovered it was only a matter of time before the Trellixians reached Earth.
