In Neal Asher's Hilldiggers, during a war between two planets in the same solar system - each occupied by adapted humans - what is thought to be a cosmic superstring is discovered. After being cut, this object collapses into four cylindrical pieces, each about the size of a tube train. Each is densely packed with either alien technology or some kind of life. They are placed for safety in three ozark cylinders of a massively secure space station.

The explorer ship Erebus is reassigned from its mission and sent to Jupiter to investigate this atrocity with Trent's international team onboard.

It’s an excruciatingly dull mission, yet it keeps him far away from the agencies that are chasing him down. However, his fortunes change, along with the other four crew members, when they discover a derelict spaceship in orbit around a binary asteroid. Scott’s share of the salvage would be enough to clear his name and start a new life.

General Burgton of the 501st Infantry Regiment believes a lack of expansion is leading the Alliance into stagnation. So when one small ship discovers a new alien race, it should be an easy decision to make contact, but what if the aliens are like the Merkiaari?

With supplies and housing stretched to the breaking point, it is clear that the refugees must be relocated down to the planet, and soon. But not to the atevi mainland, rather to the territory reserved for humans: the island of Mospheira. Tabini-aiji, the powerful political head of the atevi, tasks his brilliant human diplomat, Bren Cameron, to negotiate with the Mospheiran government.

Gunnery Sergeant Torin Kerr had been the very model of a Confederation Marine. No one who'd ever served with her could imagine any circumstance that would see her walking away from the Corps. But that was before Torin learned the truth about the war the Confederation was fighting...before she'd been declared dead and had spent time in a prison that shouldn't exist...before she'd learned about the "plastic" beings who were really behind the war between the Confederation and the Others. That was when Torin left the military for good.

He must leave Argus Station to stage a dangerous rescue - but mutiny is brewing onboard, as Saul's robots make his crew feel increasingly redundant.

Generations ago, nine ships headed into the unknown to explore a distant star called LQ Pyx. Eons later, the convoy has returned to LQ Pyx to begin work on the Web, the alien megastructure that covers the star. Is it a Dyson Sphere, designed to power a civilization as everyone believes - or something far more sinister? Meanwhile, Planet United's littlest convoy, long thought to be lost, reemerges in a different sector of deep space. What they discover holds the answers to unlocking the Web's greater purpose.

But Mia has some very good reasons why she left her old life on Earth behind.

In 2088, humankind is at last ready to explore beyond Earth's solar system. But one uncertainty remains: Where do we go? Astrophysicist Reggie Straifer has an idea.

The enigmatic Greys have returned, bearing a host of stunning revelations regarding their role in Earth’s history, the Pelarans, and humanity’s place in the cosmos. Griffin, openly declaring his allegiance to both Terran Fleet Command and the world he has helped to build, agrees to accompany the Grey ship Ethereal on a high-risk recruiting operation spanning thousands of light years. Their mission: enlist the help of enough Guardian spacecraft to put an end to the out-of-control, tyrannical AI before its forces can reach Earth.

Having successfully repelled the Resistance incursion into the Sol system, Terran Fleet Command must now deal with the far-flung worlds of the Sajeth Collective, which sponsored the attack. Task forces are dispatched to Damara and Lesheera to begin the first human blockades of entire planets. With the only ships fast enough to quickly bring the fight to the enemy's doorstep, TFC must do so alone, leaving only minimal forces behind to safeguard the Earth.
