Anomaly (Legacy War #7) – John Walker

Humanity has unlocked the secrets of the Orbs but the race to collect another of the powerful devices has put them on a collision course with their enemy, the terrorist group known as the Tol’An.

One final Orb remains at large in the wild and the Gnosis is dispatched to get it. Lost somewhere in a space station on the edge of civilized space, early intelligence reports suggested it would be a milk run…until a team of Pahxin technicians went missing there. Altering their mission parameters to include rescue, they load up an extra team of marines and head off on the mission.

Meanwhile, back on Earth, AIA operative Christina Dawson closes in on the traitor selling out humanity to the Tol’An. Her people have located an old military base currently occupied by the mercenary group responsible for attacking Gamma Alpha. She gathers a former marine and newly appointed AIA agent to investigate in person.

Deliverance (Forgotten Colony #1) – M.R. Forbes

The war is over. Earth is lost. Running is the only option. It may already be too late.

Caleb is a former Marine Raider and commander of the Vultures, an elite search and rescue team that’s spent the last two years pulling high-value targets out of alien-ravaged cities and shipping them off-world.

Now he’s on the last starship out, under orders to join forty-thousand survivors on their journey to a new home. It’s not the mission he wants, but it’s a mission he’s doing his best to accomplish. When Caleb meets the colony’s head sheriff, she represents an opportunity for a fresh start and a chance to leave his old life behind for good…

Only the mission will be harder to complete than either of them realize.

And the colonists will need the old Caleb more than he ever imagined…

Devastator (AI Fleet #2) – Isaac Hooke 

Jain thought he’d never go back.

Ten years had passed since he last had dealings with humans and their machines. He was happy. He’d built a base for himself and his Void Warriors around the barren moon of a gas giant, where they planned to live out their immortal days in peace.

And then humanity came looking for them.

Hunting them.

Now they have no choice but to return.

But what they find waiting for them in human territory will make them wish they’d never left their new home.

The Lost Star Gate (Lost Starship Series #9) – Vaughn Heppner

The Swarm is coming!

This time, enemy science vessels study us as Hive Masters gather hundreds of thousands of starships for an avalanche invasion.

Instead of facing massed bug fleets in hopeless battle, we have a desperate plan: use a Builder nexus, create a hyper-spatial tube and send suicide-ships thousands of light-years into Swarm territory. There, our ships must find and destroy the nexuses that are the only way back home, all in order to stop the bugs from using the nexuses to reach Human Space.

Despite the grim mission, Captain Maddox is determined to bring his people back. But deep in the Sagittarius Spiral Arm, disaster strikes. All alone in the stellar night, the crew must face a primordial alien that even the Builders feared and the Swarm avoids.

Now begins a deadly battle as Maddox, the crew and Galyan are pitted against a horror of legendary evil as a Swarm battle fleet waits to annihilate the victor.

Luck is Not a Factor (Four Horsemen Tales #6) – edited by Chris Kennedy and Mark Wandrey

It’s the Twenty-Second Century. The galaxy has opened up to humanity as a hyperactive beehive of stargates and new technologies, and we suddenly find ourselves in a vast playground of different races, environments, and cultures. There’s just one catch: we are pretty much at the bottom of the food chain.

What do you do when the odds are stacked against you? Mercs plan, strategize, and sometimes even scheme, but there is one thing they all believe—luck is never a factor.

Unless it is.

Enter the Four Horsemen universe, where only a willingness to fight and die for money separates Humans from the majority of the other races. Edited by bestselling authors and universe creators Chris Kennedy and Mark Wandrey, “Luck is Not a Factor” includes all-new stories in the Four Horsemen universe by a variety of bestselling authors—and some you may not have heard of…yet. The nineteen authors take on various aspects of the universe, giving you additional insight into a galaxy that isn’t at war…but definitely isn’t at peace. There’s only one thing for sure—anything’s possible for a fistful of credits!

The Roundabout (The Only City Left #3) – Andy Goldman

The Roundabout has given Earth one week to deliver to it the members of the Fifth House or face planetary destruction. In an abandoned city the size of a planet, and facing off against god-like opponents, this will be no simple task for our three groups of heroes.

Allin and Copper are captives of the four remaining members of the Fifth House. To fight them, they must first work together against the Roundabout.

Tyena is joined by a ghost, a treasure hunter, and the mind of her worst enemy inside a cat’s body. This unlikely group will need to navigate through and across the planet before they can even try to rescue Allin and do the Roundabout’s bidding.

Emperor Tumble’s first duty is to keep his citizens safe as they flee the Invasion of Pudlington. Saving the planet comes in at a distant second on his list of priorities.

Above all their heads hovers the fleet of Roundabout daggerships, waiting to see if Earth can save itself or must be annihilated.

Rumors of War (Stellar Main #2) – Richard Tongue

After destroying the pirate flagship Fortuna, Captain Victoria Carter and her crew were hailed as heroes across the Stellar Main, but though a great battle was won, she knows that her private war is far from over.

The leaders of the criminal gang escaped, fleeing into deep space to a hidden base lost somewhere among the stars, plotting their revenge against those who drove them into exile, and fermenting a conspiracy that could shake all of human space to its foundations, and launch a civil war that could destroy the Commonwealth forever.

With untold millions of lives at stake, Captain Carter and the crew of Pandora must assemble a rag-tag battle fleet and face off the pirates, or watch as the galaxy collapses into chaos and anarchy…

Seeds of Gaia – Rick Partlow

Revenge is heading to Earth at the speed of light…

The Gaia probes left a dying Earth millennia ago in a bold effort to spread life to a lifeless universe.

Unfortunately, not all of those worlds were uninhabited…

The aliens watched their world die to swarms of nanite terraformers, but with their last breath they launched a terrible, unstoppable weapon to kill those who’d stolen their home.

Patrol Captain Sam Avalon is the first human to encounter it, a missile the size of an asteroid, tearing through anything in its path, destined to impact Earth in four years and leave nothing but ashes. Together with the mysterious government operative Priscilla and the cyborg soldier Telia Proctor, they do their best to unite old enemies in a desperate attempt to save the cradle of humanity from the sins of their fathers…

Wrath of Cons (Starship Grifters #3) – Robert Kroese

Interstellar con man Rex Nihilo and his long-suffering robot sidekick Sasha are back, and they’re neck-deep in their most outrageous scam yet: selling black market planets!

Terraforming uninhabitable planets and selling them to criminals right under the nose of the repressive interstellar Malarchy is good work if you can get it, but there’s a price: as the pair’s profits soar, they find themselves on the run from… well, pretty much everybody. With the Malarchy breathing down their necks, the malevolent cult known as the Sp’ossels hot on their heels, and the Ursa Minor Mafia out for their cut, Rex and Sasha hop from planet to planet, with nothing but their wits and a motley crew of loyal friends to keep them alive.

But when their antics draw the attention of an ancient intelligence determined to wipe humanity from the galaxy, they put their moneymaking plans on hold–and team up with their biggest rival–to save the galaxy once again.

Is Rivka’s search sanctioned or has she gone rogue? Will the Federation back her play?
