About the book
From the ashes of a galaxy’s war-torn history, Captain Axel Finn faces a choice that could define its future—or destroy it.
Axel has built a fragile haven aboard his salvage ship, offering safety to a crew of misfits seeking refuge from their haunted pasts. His pacifist ideals have kept them together, but they’ve also pushed them toward financial ruin and deadly enemies.
When a desperate mission uncovers an ancient alien relic, Axel and his crew expect salvation. Instead, they awaken the legacy of the Wrath, a species that once annihilated entire worlds. Pursued by ruthless bounty hunters and shadowed by an old adversary, Axel must confront the truth about his past and the monster he’s sworn never to become.
Will he embrace his destiny—or let the galaxy burn?

About the book
A stunning tour de force filled with transcendent awe and wonder, Hyperion is a masterwork of science fiction that resonates with excitement and invention, the first volume in a remarkable epic by the multiple-award-winning author of The Hollow Man.
On the world called Hyperion, beyond the reach of galactic law, waits a creature called the Shrike. There are those who worship it. There are those who fear it. And there are those who have vowed to destroy it. In the Valley of the Time Tombs, where huge, brooding structures move backward through time, the Shrike waits for them all.
On the eve of Armageddon, with the entire galaxy at war, seven pilgrims set forth on a final voyage to Hyperion seeking the answers to the unsolved riddles of their lives. Each carries a desperate hope—and a terrible secret. And one may hold the fate of humanity in his hands.

“An unfailingly inventive narrative . . . generously conceived and stylistically sure-handed.”—The New York Times Book Review
“Simmons’s own genius transforms space opera into a new kind of poetry.”—The Denver Post

About the book
With the fourth stand-alone NeoG novel, Die Hard meets A Long Way to a Small, Angry Planet in this nail-biting, action-filled story that’s as much about found family as it is about survival when a peaceful transition of power in the Mars Orbital Station goes terribly wrong as rebels decide this is the moment to make their move, leaving two NeoG members stranded inside a ticking time bomb.
When you’re trapped in space, there’s no way out.
The mission of the Near-Earth Orbital Guard is to ensure the peace and security of the solar system. Commander Maxine Carmichael and Lieutenant Commander Saqib Vahid are at the Mars Orbital Station (MOS) to help facilitate the official handover from NeoG to Mars civilian control as part of the ongoing negotiations. Members of the extreme wings of the fight for Martian independence refuse to remain silent, and are willing to resort to violence to make their voices heard; Max and Saqib find themselves fighting for their lives. The attacks both on the MOS and the ground of Mars sets off a chain reaction that could destabilize the last few years of cautious peace.
The leader of Free Mars, Sylvia Moroz, knows better than anyone how fragile harmony is, having seen for decades the Coalition of Human Nations’ inability to negotiate for peace. Without any assurances—and knowing her splintered people all too well—anything less than complete liberation will only lead to more bloodshed. She’s not opposed to fighting, but when there’s an attempt on her life, she finds she must look for help from the NeoG and Commander D’Arcy Montaglione. The pair will have to overcome their past to figure out who they can trust and how to stop the attacks on the ground before more lives are lost.
Trapped inside the station, Carmichael and Vahid are scrambling to not only get to the bottom of the attackers’ motives, but also to simply survive. Because with the rest of the Zuma’s Ghost crew stuck down on Mars, it’s up to them to do what they can to keep the MOS from fully falling into the wrong hands…and keep Mars from descending into all-out war.

Our take
A shattered planet. A crew of outcasts. And Caiden, caught between survival and vengeance. With only a sentient ship and a few alien misfits by his side, Caiden must destroy the slavers who stole everything from him—even if it means risking everything he has left. One wrong move, and he’s history.
Choose your retailer
About the book
The planet he called home? Obliterated. Caiden’s family? Gone. His only shot at survival? A patched-up ship with a life of its own and a ragtag crew of aliens who aren’t exactly winning any popularity contests. Caiden’s about to learn that this universe is far bigger—and a whole lot stranger—than he ever bargained for. But the wonders of space have their darker corners, and Caiden has one goal: take down the slavers who wiped out his people. To do that, he’ll have to infiltrate their ranks, play the long game, and pray they don’t see through his plans. Because if he fails? He risks losing the one chance he has to get even. Can he succeed—or is he doomed to die trying?
