Our take
Retired Colonel Carl Butler wants nothing more than quiet, but when a twelve-year-old girl begs him to find her missing father, he’s pulled back into the galaxy’s most dangerous politics. On a moon ruled by rival consortiums that have already tried to kill him, Butler uncovers disappearances tied to secrets buried in perpetual darkness. From acclaimed science fiction author Michael Mammay.
Choose your retailer
About the book
In this thrilling, action-packed fourth installment in the Planetside series from acclaimed science fiction author Michael Mammay, retired Colonel Carl Butler gears up for another military investigation, full of danger, corporate intrigue, and tech people would kill for—perfect for fans of John Scalzi and Craig Alanson.
Colonel Butler has paid his dues and just wants to enjoy his retirement on a remote planet. But the galaxy has had other plans. He has been roped into searching for a politician’s missing son and an industry magnate’s missing daughter. He has been kidnapped, violated numerous laws, and caused the destruction of colonial facilities. He’s famous—or infamous, depending on who you ask—praised and reviled in equal measure across the galaxy for his exploits.
And he is determined to never let the government drag him into another investigation.
But when a runaway twelve-year-old girl whose father has gone missing asks him for help, well…it’s a lot harder to say no.
The girl’s father, Jorge Ramiro, was supposed to have been on Taug, a moon orbiting the gas giant Ridia 5, working on a dig with a famous archaeologist. But now there’s no sign of him and no record of him being there. Mining operations on the moon are run by two different consortiums, Caliber and Omicron—both of which have tried to kill Butler in the past. Butler doesn’t believe in coincidence.
Landing on Taug with his right-hand man Mac, computer genius Ganos, and an elite security squad, Butler soon finds that they’ve charged back into the crosshairs—because Ramiro is not the only who has disappeared, and the perpetual darkside of this moon is hiding more than the truth about a missing archeologist…

Colonel Arthur Hanson is thrust into command after coordinated terrorist strikes devastate the fleet in the Orion Spur, forcing the engineer at heart to lead the survivors against the attackers, with a 4.3-star rating from more than 1,900 Amazon reviewers.

Choose your retailer
About the book
They struck without warning. Now, survival depends on a man who’s never led.
Lieutenant Colonel Arthur Hanson was supposed to be an engineer, not a hero. Promoted to second-in-command aboard the CSV Margaret Thatcher, Arthur hoped for a quiet tour of duty—showing strength and keeping the peace.
He never expected a coordinated terrorist onslaught that would shatter the fleet and leave tens of thousands dead.
With the Thatcher crippled and reinforcements trapped behind political red tape, Arthur is thrust into command. Haunted by doubt but driven by duty, he must rally the broken survivors and strike back against a ruthless enemy who shows no mercy.
Because in the Orion Spur, freedom isn’t given. It’s fought for.
And aboard a ship named after the Iron Lady herself, surrender is not an option.
Perfect for fans of epic space battles, gritty heroes, and heart-pounding military science-fiction.

Across the galaxies, fate and absurdity collide in a story that questions the very purpose of existence.

About the book
A stellar new science fiction adventure from the author who redefined space opera, set in his bestselling Revelation Space universe.
For thirty years a tiny band of humans has been sheltering in the caverns of an airless, crater-pocked world called Michaelmas. Beyond their solar system lie the ruins of human interstellar civilization, stalked by a ruthless, infinitely patient cybernetic entity determined to root out the last few bands of survivors. One man has guided the people of Michaelmas through the hardest of times, and given them hope against the wolves: Miguel de Ruyter.
When a lone human ship blunders into their system, and threatens to lead the wolves to Michaelmas, de Ruyter embarks on a desperate, near-suicide mission to prevent catastrophe. But an encounter with a refugee from the ship—the enigmatic woman who calls herself only Glass—leads to de Ruyter's world being turned upside down.

Marine
Joshua Dalzelle
Sci-Fi · Military Sci-Fi · Space Exploration
Our take
War shaped Jacob Brown before he ever wore a uniform, but the mission that finally sends him off Earth exposes dangers far beyond combat. In Marine, a young recruit chases his dream of serving aboard a starship only to land on a brutal assignment that reveals hidden threats within humanity’s war with alien forces. It’s a military science fiction opener driven by survival, secrecy, and high-stakes action on hostile ground.
Choose your retailer
About the book
Aliens exist… and, as it turns out, most of them aren’t that friendly.
Jacob Brown wasn’t even born yet the first time they attacked Earth.
He was only fourteen the second time it happened.
When Earth finally came together and fielded its first spaceborne military, Jacob didn’t hesitate to volunteer. Serving aboard a mighty starship, he’d be able to defend his planet—and his family—when, inevitably, they came again.
Just as he’s about to graduate training, however, Jacob is approached by an officer from Naval Special Operation Command and given a choice: volunteer for a risky mission to a dangerous, lawless world, or give up his dream of serving in the military and go home. He has no idea why he’s being singled out in such an unusual manner, but now it's either agree to their demands or give up his dream of being on a starship.
Soon, getting his career back on the right track will be the least of his concerns when it seems like everyone—and everything—he meets is trying to kill him. When he stumbles upon a secret most people on Earth are blissfully unaware of he realizes it's not just the aliens he needs to be worried about.
"Marine" is the first book in the Terran Scout Fleet Series by the bestselling author of the Omega Force Series and Black Fleet Trilogy.

Sci-Fi · First Contact
A rescue crew arrives on an alien moon to find survivors living beneath the ice and a mystery that is killing them.

The Minotaur
Peter Cawdron
Sci-Fi · First Contact · Hard Sci-Fi · Space Exploration
Our take
A rescue crew arrives on an alien moon to find survivors living beneath the ice and a mystery that is killing them. As deaths mount, understanding the alien life becomes a matter of survival. This thoughtful first-contact novel blends suspense and psychology, earning 4.5 stars on Amazon and praise for its classic science fiction sensibility.
Choose your retailer
About the book
Life has been found beneath the icy shell of the moon of a gas giant orbiting a red dwarf at a distance of 11 light-years from Earth. When the crew of the original exploration mission crashes on the alien moon, a rescue ship is launched. Arriving decades later, the crew of the Kelvin finds a colony of survivors living in the labyrinth of caves beneath the surface of the moon. When people start dying, they realize they need to unravel the secrets of this alien world and the mystery of the minotaur.
The Minotaur is a tribute to the 1961 classic Solaris, written by Stanislaw Lem, and considers the psychological impact of examining an exotic alien life form unlike anything ever encountered on Earth.
FIRST CONTACT is a series of stand-alone novels that explore humanity's first interaction with extraterrestrial life. This series is similar to BLACK MIRROR or THE TWILIGHT ZONE in that the series is based on a common theme rather than common characters. This allows these books to be read in any order. Technically, they're all first as they all deal with how we might initially respond to contact with aliens, exploring the social, political, religious, and scientific aspects of First Contact.
Peter Cawdron is a fan of such classic science fiction writers as Philip K. Dick, Arthur C. Clarke and Michael Crichton and their influence on his style and storylines is readily apparent. His forays into hard science fiction could best be described as informative science fiction or enjoyable science fiction. They focus on character and plausibility.

About the book
War has found the stars again. On the distant planet of Darien, the battle for humanity’s future has already begun.

Within that prison lie entities so ancient and powerful that their awakening could consume every sentient world.
Michael Cobley’s The Orphaned Worlds delivers sweeping space opera on a cosmic scale—where politics, faith, and survival collide in a war that spans the stars.
