HALO: Contact Harvest

It's 2552. Having barely escaped the final battle for Reach against the vast alien alliance known as the Covenant, the crew of the Pillar of Autumn, including Spartan John-117 - the Master Chief - and his AI companion Cortana, is forced to make a desperate escape into slipspace. But their destination brings them to an ancient mystery and an even greater struggle. 

The 26th century. Humanity has expanded beyond Earth’s system to hundreds of planets that colonists now call home. But the United Earth Government and the United Nations Space Command is struggling to control this vast empire. After exhausting all strategies to keep seething colonial insurrections from exploding into a full-blown interplanetary civil war, the UNSC has one last hope.    

The Covenant has collapsed after a long, brutal war that saw billions slaughtered on Earth and her colonies. For the first time in decades, however, peace finally seems possible. But though the fighting's stopped, the war is far from over: it's just gone underground. The UNSC's feared and secretive Office of Naval Intelligence recruits Kilo-Five, a team of ODSTs, a Spartan, and a diabolical AI to accelerate the Sangheili insurrection.

Saskia, Dorian, Evie, and Victor aren't exactly friends at their small high school on the middle-of-nowhere colony world of Meridian. Each has their own problems, from absent parents to supporting their family, getting into a good college to making the next hit holo-film. But those problems were nothing next to the threat now facing their world: The alien alliance known as the Covenant is laying siege to Meridian. With their village in flames, the four teens find themselves stuck aboveground, locked out of the town shelter where the rest of the survivors are gathered. 

In the wake of apparent self-destruction of the Forerunner empire, two humans - Chakas and Riser - are like flotsam washed up on very strange shores indeed. Captured by the Master Builder, misplaced during a furious battle in space, they now find themselves on an inverted world where horizons rise into the sky, and where humans of all kinds are trapped in a perilous cycle of horror and neglect. For they have become both research animals and strategic pawns in a cosmic game whose madness knows no end....

On the planet Tython, the ancient Je’daii order was founded. And at the feet of its wise Masters, Lanoree Brock learned the mysteries and methods of the Force - and found her calling as one of its most powerful disciples. But as strongly as the Force flowed within Lanoree and her parents, it remained absent in her brother, who grew to despise and shun the Je’daii, and whose training in its ancient ways ended in tragedy. Now, from her solitary life as a Ranger keeping order across the galaxy, Lanoree has been summoned by the Je’daii Council on a matter of utmost urgency.

Blackhawk: a wanderer, a man running from a dark and sinister past. A genetically-engineered warrior, a capable and accomplished killer, he is also a lost soul, a man who has fled to the deepest reaches of space seeking his true identity. The Far Stars: the farthest extent of human habitation in the galaxy, a sector of a hundred inhabited worlds, it is a dangerous expanse full of pirates, mercenaries, and cutthroats.

Jake Price has always dreamed of joining the Darkstream military like his father before him. When he’s told his gaming scores are good enough to qualify him for a brand-new training program designed to find recruits talented enough to pilot humanity’s first mechs, he can hardly believe it. There are hundreds of other recruits competing for the same eight jobs, and they’re all as skilled as he is. But Jake refuses to give up, because humanity is facing its greatest threat yet. If someone doesn’t step up, it could all be over for the human species. Contains the complete series.

The year is 2033. The world has been reduced to rubble. Humanity is nearly extinct and the half-destroyed cities have become uninhabitable through radiation. Beyond their boundaries, they say, lie endless burned-out deserts and the remains of splintered forests. Survivors still remember the past greatness of humankind, but the last remains of civilisation have already become a distant memory. Man has handed over stewardship of the earth to new life-forms.

Jupiter, thrown off orbit, will destroy Earth in less than a century. Jon Ryan volunteers for the most ambitious, desperate mission ever conceived: His consciousness must be transferred into an experimental android host, where he'll live an immortal - and lonely - life.

An alien species has vowed a holy war to eliminate all humans, either on Earth or wherever they might run. Only Jon can protect humans from their enemies.
