About the book
When unforeseen circumstances during an innovative—and unsanctioned—commercial asteroid-mining mission leave two crew members stranded, those who make it back must engineer a rescue, all while navigating a shifting web of global political alliances and renewed Cold War tensions. With Earth governments consumed by the ravages of climate change and unable to take the risks necessary to make rapid progress in space, the crew must build their own nextgen spacecraft capable of mounting a rescue in time for the asteroid's next swing by Earth.
In the process they'll need to establish the first spin-gravity station in deep space, the first orbiting solar power satellite and refinery, and historic infrastructure on the moon's surface—all of which could alleviate a deepening ecological, political, and economic crisis back on Earth, and prove that space-based industry is not only profitable, but possibly humanity's best hope for a livable, peaceful future.

About the book
Where is everyone?
Twenty-five years ago, a message from deep space fractured Humanity. The transmission? Only one word: “Hello.” Half of Humanity wanted to explore it, while the other half wanted to hide. Despite the division, a megaship, called the Traveler, followed the signal through space. Its disappearance only solidified the divide and led to the bloodiest civil war across Humanity, the Sapien War. Ten years later, Humanity met aliens, but not the ones who sent the signal.
Today, Kasey Mako, one of the Traveler’s sons, investigates mysterious phenomena plaguing the galaxy. A virus and missing colony are just the tip of the iceberg for Kasey and the Galactic Union. As Kasey’s team of aliens and humans delve into the mystery, they discover these events aren’t random; they’re connected. They discover a more sinister plot that threatens not only the Union, but the entire galaxy.

Forager
Sci-Fi · Teen + Young Adult
Our take
Ethan hides a mutation that could get him killed, but surviving Melbourne’s ruins grows harder when he rescues a bold, enigmatic girl. As Skel savages grow stronger and their town faces destruction, Ethan must uncover secrets—hers and his own. Can he protect his life and his people, or will his secrets doom them all?

About the book
In a post-apocalyptic world where mutations mean death, Ethan Jones hides a dangerous secret: a unique ability that helps him survive Melbourne’s treacherous ruins and the deadly Skel savages who stalk them. Life in his rigid town is hard enough, but everything changes when he rescues a mysterious Japanese girl whose bold defiance of convention puts both their lives at risk.
Her strange behavior—and their inexplicable connection—raise questions Ethan can’t ignore. As the Skel grow more organized and armed with advanced technology, a sinister plot begins to unfold, threatening the town’s fragile existence. Ethan must protect his secret, uncover the truth behind the girl’s intentions, and stop the Skel’s deadly advance. If he fails, the cost will be far greater than his life alone.

Our take
When the world collapses without warning, survival becomes an act of faith. After the grid falls and raiders claim the forests, Sandal grows up navigating hunger, violence, and constant flight. Her brief connection to Jacob offers hope, then loss. Now alone in a broken world, she must rely on resilience and resolve to survive what remains.

Choose your retailer
About the book
The world was dark, the grid down—probably for good. No one knew why.
Raiders held the upper hand, combing the forests in search of what they needed. Weapons were in short supply, as was food and clean water.
Sandal had only known the reality of trying to stay one step ahead of danger. But when she met Jacob things changed. He was her lifeline, her one tether. And when they parted, her hope vanished along with him.
But that was then. Now she must find her way out of a world gone mad, or die trying.

Shizuka Satomi made a deal with the devil: to escape damnation, she must entice seven other violin prodigies to trade their souls for success. She has already delivered six.
When Katrina Nguyen, a young transgender runaway, catches Shizuka's ear with her wild talent, Shizuka can almost feel the curse lifting. She's found her final candidate.
But in a donut shop off a bustling highway in the San Gabriel Valley, Shizuka meets Lan Tran, retired starship captain, interstellar refugee, and mother of four. Shizuka doesn't have time for crushes or coffee dates, what with her very soul on the line, but Lan's kind smile and eyes like stars might just redefine a soul's worth. And maybe something as small as a warm donut is powerful enough to break a curse as vast as the California coastline.
As the lives of these three women become entangled by chance and fate, a story of magic, identity, curses, and hope begins, and a family worth crossing the universe for is found.

The Stars too Fondly
LGBTQIA+ · Sci-Fi
Our take
Cleo and her friends didn’t mean to steal a spaceship—yet a rogue dark matter engine sends them hurtling toward Proxima Centauri with a sarcastic hologram of the missing captain as their guide. As physics bends and old mysteries resurface, Cleo’s prickly bond with Billie deepens into something far more dangerous and tender. A sapphic, high-spirited space adventure from Emily Hamilton.
Choose your retailer
About the book
In her breathtaking debut—part space odyssey, part sapphic rom-com—Emily Hamilton weaves a suspenseful, charming, and irresistibly joyous tale of fierce friendship, improbable love, and wonder as vast as the universe itself.
So, here’s the thing: Cleo and her friends really, truly didn’t mean to steal this spaceship.
They just wanted to know why, twenty years ago, the entire Providence crew vanished without a trace. But then the stupid dark matter engine started all on its own, and now these four twenty-somethings are en route to Proxima Centauri, unable to turn around, and being harangued by a snarky hologram that has the face and attitude of the ship’s missing captain, Billie.
Cleo has dreamt of being an astronaut all her life, and Earth is kind of a lost cause at this point, so this should be one of those blessings in disguise that people talk about. But as the ship gets deeper into space, the laws of physics start twisting, old mysteries come crawling back to life, and Cleo’s initially combative relationship with Billie turns into something deeper and more desperate than either woman was prepared for.
Lying somewhere in the subspace between science fantasy and sapphic rom-com, The Stars Too Fondly is a soaring near-future adventure about dark matter and alternate dimensions, leaving home and finding family, and the galaxy-saving power of letting yourself love and be loved.

To Sleep in a Sea of Stars
Sci-Fi
Our take
During a routine mission, Kira Navárez finds an alien relic that should have been a dream come true. Instead, it unleashes a nightmare. With war erupting across the stars and humanity on the brink, Kira may be the only one who can stop the coming destruction. To Sleep in a Sea of Stars is a gripping space epic from Eragon author Christopher Paolini.
Choose your retailer
About the book
She dreamed of new worlds. She awakened a nightmare.
Kira Navárez’s life as a space explorer was supposed to be simple—survey planets, report findings, and move on. But everything changes when she discovers an alien relic buried beneath the dust of an uncolonized world. At first, she’s thrilled. Then the dust begins to move.
What Kira has uncovered is far more than an artifact—it’s a catalyst. War erupts among the stars, and humanity teeters on the brink of annihilation. As she is thrust into the heart of an interstellar conflict, Kira must push beyond the limits of what it means to be human.
A New York Times and USA Today bestseller, To Sleep in a Sea of Stars is a breathtaking space opera of discovery, transformation, and the fate of the galaxy.
